Microsoft Fax is supported in Windows 95 and will be supported in the shell update release of Windows NT 3.51. There is also support in Windows for Workgroups 3.11 (where Microsoft Fax was known as Microsoft At Work ). A fax service provider written to the LMI will work on all these platforms. For this discussion of the LMI, no distinction is made between operating environments. The Logical Modem Interface divides Microsoft Fax support in Windows into two parts: a fax transport that sits above the LMI, and one or more LMI providers that sit underneath. The fax transport is a messaging provider integrated with mail (MAPI) that can expose faxing capabilities to the user in many ways. Most fundamentally, faxing capability is exposed through the Microsoft Mail or Microsoft Exchange Send Note form, where fax is treated as just another valid address type by the user. But faxing capability is also exposed to the user through a print to fax mechanism hooked into the printing system (this user interface is more typical for alternative fax packages). In the new Windows shell, fax is also exposed through a send fax wizard. Regardless of the method chosen by the user to compose a fax, once sent by the user the fax message ends up as a message in the mail store. In general, any outbound message in the store is extracted by MAPI, and, if addressed to one or more fax recipients, the message is handed over to the fax transport for delivery. The fax transport performs several types of processing on a fax message after receiving it from MAPI. The objective of this processing is to create a data stream that contains the actual bits that need to be sent across the wire. (It is assumed that in most cases, a fax will be sent over a PSTN connection. This need not always be so, such as in the case of a NetFax server.) The format of this data might be one of the standard MH, MR, or MMR formats; or it might be the Microsoft Fax linearized file format, which allows multiple, binary attachments. The transport intelligently decides which format or formats to generate (more than one may be generated) based partly on cached (or unknown) capabilities of the recipient, and partly on preferences expressed by the user. Especially in cases where the transport cannot decide the best format, it may generate several, postponing the actual decision of which to send until run time. Once the appropriate formats have been generated, the main work of the fax transport is done. From that point, responsibility for sending the fax belongs to the active LMI provider. The user could have several LMI providers installed, such as a local modem and a network fax service provider, but only one can be active at a time. The fax transport has no knowledge of any physical modem or phone line. It only knows about the existence of a logical modem. The transport can submit jobs to be sent over this modem without worrying about how they will be sent. An LMI provider can accept these jobs and complete them in any way, including by forwarding the data to a different machine (which could be running a custom operating system) where a physical fax modem is installed. Once it completes sending the fax, the LMI provider must return the results of the send to the sending fax transport. Because sending faxes and communicating between machines can be time-consuming, the interface is completely asynchronous. None of the calls into the interface require blocking of the fax transport while the LMI provider performs some operation. The LMI provider benefits from this division of labor because all of the intelligence is kept common in the fax transport, including all knowledge about keeping capabilities, rendering attachments to the message, getting data from OLE objects, and so on. The LMI is designed so that all structures and data passed through the interface are already marshaled into blocks of BYTES. This simplifies the implementation of the LMI provider in the case where the provider is used with a network front-end processor and where the actual fax call is not made in the same process context as the provider interface. The LMI provider must parse the structures, dial the numbers, and send the appropriate format across the connection. To communicate with other Microsoft Fax-enabled machines over a PSTN connection, the LMI provider must be able to talk the Microsoft Extended Fax Protocol (MEFP) on the wire. MEFP is a set of NSF extensions to the ITU T.30 protocol; the details of this protocol are documented elsewhere. The current document assumes that the LMI provider can talk to Microsoft Fax clients and decipher their capabilities in order to make intelligent decisions about which format is to be sent. There is a wide range of functionality an LMI provider may choose to provide. At the simplest, an LMI provider can decide to only provide send-fax services, with no capability of queuing, scheduling, and so on. A more complex LMI provider can have it's own phone books, generate cover pages, print incoming faxes, do inbound routing of other faxes, do load balancing with multiple hardware phone lines, and much more. The LMI encourages vendors to differentiate their offerings. The same fax transport can talk to an LMI provider with any kind of functionality. The fax transport makes dynamic decisions based on capability flags that are part of the LMI. Except for a few configuration functions, the interface is guaranteed to be called from a single process context. However, the client software can consist of multiple threads, each of which may call portions of this interface. It is possible for a second API to be called while still in the middle of a previous call (the calls would be in different thread contexts). This is important. It means that the LMI provider must protect itself from reentrancy issues. A logical modem is treated as a single queue to which jobs can be sent. There is not necessarily a one-to-one correspondence between a logical modem and a physical modem. An implementation can hide several modems behind a single queue and do load balancing among the modems. Important: Unless explicitly stated otherwise, an LMI provider should not present any user interface in any interface calls. Many of these calls are made in the background and are not expected to put up UI (including message boxes). @topic Overview of the LMI Provider Interface | This document describes the services a fax provider must implement to act as a fax provider to a Microsoft Fax client through the LMI. The interface has several main components. The parts are installation, configuration, queue administration and status, sending faxes, receiving faxes, and uploading documents and cover pages. Each of these is covered in detail in the following sections. It is useful to present a high-level overview of how the fax transport calls into the Logical Modem Interface. At first, the transport's configuration user interface calls and to control which modems exist in the list of available modems. It also calls to make any necessary configuration decisions. When the fax transport initializes, it calls and . The transport can then send faxes with . The transport polls for the status of sent faxes with and looks at the provider's queue with . To abort or reschedule a fax that has been sent but has not yet left the queue, the transport can call and . The transport polls for received faxes with . Finally, the transport calls and when it is time to shut down. A useful example to study for understanding the flow across the LMI is the simple case of a send on one machine leading to a receive on another. A send starts off as a note composed in a mail client by the user. In this example, the user types in some text and attaches a bitmap. The user addresses the note to a single fax recipient at the phone number 555-1234 and chooses to send the note in the best format possible at the cheap-rate time. When the note is ready, the user sends the note (this really just saves the message to the store). The message is then picked up from the store and is handed to the fax transport, because the message has a fax recipient. The fax transport looks into its capability database for the number 555-1234, but (in this example) finds no entry. Because the user chose to send the message in the best format possible, the fax transport converts the message into two formats: a rendered, MMR version (images only) and a linearized file-format version (binary file). For the rendered version, the transport itself renders the text; calls Paintbrush to render the bitmap file; and finally generates a file combining the rendered images, to which it attaches a linearized header. For the linearized version, the transport calls the linearizer, which assembles the binary attachments as-is into a file with a linearized header. After creating the two separate files, the fax transport calls in the LMI provider. In the call, the transport passes in the details of the job as well as the file name for each of the two formats that were generated. In response to the call, the LMI provider examines the details of the send job. Seeing that the fax (in this example) is to be sent at cheap rates, it leaves the job on its internal queue. The fax transport periodically polls the LMI provider for the status of the fax. When cheap times roll around, the LMI provider connects to 555-1234 using a local modem and sends the appropriate format (the MMR file if the receiver is a G3 fax machine, or the linearized file if the receiver uses Microsoft Fax). The next time the fax transport calls after the fax is sent over the wire, the LMI provider returns the final status of the send job. Upon receipt of this status, the fax transport passes it on to the user, typically generating a Non-Delivery Report (NDR) if there was an error, or moving the message into the Sent Mail folder if the send was successful. Received faxes are available immediately to the LMI provider on the remote machine, since it is the one picking up the phone. The LMI provider then has to decide to which client the message needs to be routed. For reception of G3 faxes, intelligent decisions are not possible since there is no structured routing information; routing to some default client is probably best. For Microsoft Fax messages, the LMI provider can interpret the linearized header (using some helper functions) and extract the Microsoft Fax address of the recipient. If this address contains a routing name, the name can be matched to a list of clients and the fax can be easily routed. Once the LMI provider has decided on the recipient client, it waits for that client's fax transport to regularly poll for new faxes. When polled (by a call to ), the provider creates a file with the received data in an appropriate format. If the fax was received from a G3 fax machine, the provider can use helper functions to construct a file starting with a linearized header, followed by AWG3 page headers, finally followed by the data. For linearized file-format faxes, the exact data received is passed in. Finally, the client fax transport parses the data file (of whichever format) and creates a new message in the mail client Inbox containing the data in a format the user can view. @topic Installation | Installing a new LMI provider module is a two step process. First, the installation program must create an entry in the MSATWORK.INF file as defined below. MSATWORK.INF file format: [External Devices] \=\ . . \=\ [\] Display Name=\ DLL Name=\ Flags=\ [\] Display Name=\ DLL Name=\ Flags=\ Explanation: \: Name of the section of the below device. \: Description of the device, for INF-file purposes only, not used anywhere else. Display Name: Name of the device. This name will be displayed in the AddDevice dialog listbox. DLL Name: Name of the DLL that services this device. Flags: Currently will be zero. Can be used for various device capabilities, like whether this device allows setup, etc. Example: [External Devices] IFAX=An intelligent fax machine AcmeFax=A future fax provider [IFAX] Display Name=Intelligent fax machine DLL Name=ifax32.dll Flags=0 [AcmeFax] DLL Name=acme32.dll Next, when the user installs a new fax modem from the configuration interface, the user is presented with a list of all strings from the Display Name section of the MSATWORK.INF file. When the user chooses Display Name, is called to allow the LMI provider to put up a dialog box that asks the user to choose a logical modem from that LMI provider. returns a string representing the logical modem the user has selected. This string is then displayed in the list of currently available modems. The user can choose the current default fax modem from this list. @topic Configuration | The user is allowed to configure any of the available fax modems (logical modems). is called for the appropriate LMI provider. This function allows the user to do whatever remote configuration options are permitted. These may be divided into user-configurable and administrator-configurable options. In general, there should be very few user configurable options. For administrator options, this function should probably use some kind of password protection. @topic Initialization | When the fax transport starts, the function is called for the appropriate LMI provider. Then, the function is called for the modem the client wants to use. This function intializes the logical modem and return to the client a handle to the modem, as well as the modem’s capabilities. The capabilities include support for advanced features and are used by the client to decide what kind of operations are supported by the LMI provider. An example of an important capability is whether or not the modem is Microsoft Fax enabled. The phone number of the modem is some other information returned by this call. Several logical modems may be initialized at the same time. All operations on a modem use the handle returned by the call. @topic Queue Management | To allow the user to see up-to-date status for all the jobs of an LMI provider, functions have been defined to let the client monitor and administer the provider's queue. is called whenever the user wants to see the queue. This function gives access to a specific set of information about each job in the provider's queue. The information is displayed in a uniform manner by the fax transport. To allow value-added, extended-status displays, arbitrary binary information can also be passed back as part of the status. If the user wants detailed status on a particular job, is called with this binary information to display more detailed status. If the user wants to cancel or reschedule jobs, the functions and may be called. @topic Sending Faxes | When a fax is to be sent, the transport assumes all responsibility for rendering the appropriate formats for transmission. The transport maintains a cache of the capabilities for all fax machines it has talked to before and uses the database to attempt intelligent decisions about the most efficient format to be sent. The transport also takes into account explicit user preferences. There are three different formats that can be sent. The first is for sending to standard fax machines and consists of MH, MR or MMR data. The second format is a linearized EFAX message containing only image data. The third format is a linearized EFAX message containing binary data. All three formats are always preceded by a linearized header describing the file. See Microsoft At Work Linearized File Format for details of this header. Details of the fax file format are in AWG3 File Format. When the fax has been sent, the LMI provider reports the final status for the job via . This function is polled periodically by the fax transport. Along with the final status, the Provider must return the newly found capabilities of all the recipients of the fax. The client can also ask for attention using the function. Poll requests are also submitted using LMI_SendFax. Fields in the LMISENDJOB structure provide the information for the poll request. @topic Receiving Faxes| All received faxes need to be routed by the fax transport to the appropriate LMI provider. The Microsoft At Work fax transport polls for received faxes using the function. As with sent faxes, received faxes can be in any one of three formats. The header for the file describes the format and gives information about the recipients of this message. All formats MUST have a linearized header describing the format and contents of the message. See Microsoft At Work Linearized File Format for details of this header. Details of the Fax file format are in AWG3 File Format. ****/ /******** @doc EXTERNAL SRVRDLL DATATYPES @topic Microsoft At Work Address | This section describes the Microsoft At Work address format. In its most common form, this consists of a name and a phone number. The phone number is assumed to begin at the last @ in the address. In its more complex forms, the name could contain more routing information. Ideally, the phone number in the address is in the canonical form. This consists of +\[\]\[\|\]. Other important things to note: An @ can be escaped by using a backslash, and a suffix may be added to the canonical number by using a \| symbol after the number and following that with the suffix. @ex Some Examples: | A simple Micsosoft At Work Address might look like JohnDoe@+1(206)5551212|$999 which would indicate that after dialing the number, we should wait for a beep and dial a 999. THe receiving number would then route to JohnDoe. If the number is an IFAX machine, John would have an account with the login JohnDoe, or if the number was a PC, JohnDoe would be the email alias for his account. In general, the part of the address must be interpreted by the receiving machine and can contain any routing information necessary for inbound routing by this machine. *********/ /**** @doc EXTERNAL SRVRDLL OVERVIEW @topic Constants| The following section contains a list of predefined return codes, error codes, and other predefined values used throughout this document. ****/ /******** @doc EXTERNAL SRVRDLL DATATYPES @type NONE | LMI_RETURN | Return codes for LMI provider API's. @emem LMI_SUCCESS | No error - function was successful. @emem LMIERR_CONNECT_FAILED | Connection to Provider failed.

This error consists of three parts: an error code, an extended error code, and error specific data (in some cases). The extended error code must be set to T30_UNKNOWN if the means for setting a more meaningful error are not available. A value of zero in the data field implies that there is no valid data for this error. In those cases where the extended error or data fields are unused, they must be set to zero. This is to allow these fields to be used in the future. @emem Error Code | The low BYTE of the low word of the error is the error code. Use the macro GetErrCode(error) to extract this BYTE. The error codes defined are: @flag T30_CALLFAIL | An error occured during actual transmission of the fax. Detailed error status can be determined from the extended error field. @flag T30_DIALFAIL | An error occured during dialing the fax number. Detailed error status can be determined from the extended error field. @flag T30_ANSWERFAIL | An error occured during answering of a phone call. Detailed error status can be determined from the extended error field. @flag T30_NOMODEM | The Provider could not find any hardware modem to send the fax over.

In general, logical modems should try to be as robust as possible, ignoring characters which are not understood. This error code should only be used for cases where the string is so obviously malformed that there is no point even attempting to dial. @emem Extended error codes for T30_ANSWERFAIL | The provider does not have to report receives which failed in the answering phase itself.

A common case causing this error is if a receive is in progress. The client will typically retry the call at a later time, transparently to the user. @flag PORTBUSY_OTHERAPP | The device or port is used by some other application. @emem Extended error codes for T30_CALLFAIL | This is likely to be the most common error, and very detailed error codes are defined for it.

This is done so they can be easily stored in a file or transmitted as a block across the network. Most structures have two size fields. The HeaderSize field gives the defined size of the structure, which is used for versioning the structure. If the structure is expanded in the future, this size can be used to maintain backward compatibility. The TotalSize field indicates the size of the whole structure along with all its data. All strings and other variable-length data items such as structures are represented in the structure by an offset from the beginning of the structure. The actual data for these elements begins at that offset. The length of the data is indicated by the item itself. If it is a string, it is null-terminated. If it is another structure, the size fields will convey this information. All files referenced in the structures are created in the spool directory specified in LMI_InitProvider. ****/ /******** @doc EXTERNAL SRVRDLL DATATYPES @types LMICUSTOMOPTION | Overlay of LMI Custom Option data.
