       faxaddmodem - configure a modem for use with HylaFAX


       /usr/sbin/faxaddmodem [ -s speed ] [ -f ] [ tty ]


       faxaddmodem  is  an  interactive  shell  script that does the necessary
       setup work to configure a modem for use by the  HylaFAX  software.   To
       enable  use of the configured modem one must either use the faxmodem(8)
       program or configure the  init(8)  program  to  startup  a  faxgetty(8)
       process  for  the  newly  configured modem.  In either case the faxq(8)
       program must also be running if outbound services are to be provided.

       If  the  serial  port  name  is  not  specified  on  the  command  line
       faxaddmodem will prompt for it.

       The  configuration  work done by faxaddmodem falls into two main areas:
       creating the necessary files to run a  facsimile  server  process,  and
       defining the contents of the configuration database file.  The hylafax-
       config (5) manual page has an in-depth description of the  contents  of
       the configuration file and should be consulted when installing a modem.

       Many aspects of configuring  a  modem  are  operating  system-specific;
       faxaddmodem  uses  a collection of support routines and parameters that
       are generated by the faxsetup(8) program.  If faxsetup has not been run
       on a machine prior to running then faxaddmodem will abort.

       faxaddmodem  can  be  used  to  install  a new modem or re-configure an
       existing modem.  In the latter case it will propagate all  the  server-
       related  configuration  parameters from the existing configuration file
       to the new configuration file.  These parameter include items  such  as
       the  phone  number,  area code, and tracing control parameters.  Modem-
       related configuration parameters are, however, not propagated.  Instead
       faxaddmodem  deduces the type of modem attached to the specified serial
       port and then sets up the  configuration  parameters  using  a  set  of
       prototype  configuration  files that have been tested with like modems.
       If a modem is to be installed for which there is no existing  prototype
       file, faxaddmodem will work from a comprehensive template of parameters
       that can be edited either during or after the installation process.

       faxaddmodem deduces the type of modem attached to the  serial  port  by
       sending commands to the modem at a fixed speed.  By default, this speed
       is deduced by sending commands to the modem at successively  decreasing
       speeds  until  a  valid  response  is received.  Alternatively, a fixed
       speed can be specified from the command line with the -s option.

       Because faxaddmodem needs to read and write the modem  that  is  to  be
       installed  it  will  not  proceed  with an installation if the modem is
       locked for use by another process.  If the modem is not locked and  the
       -f  option  is used, then the system's fuser(1) command will be invoked
       to ensure that faxaddmodem is the only process using the modem.

       Finally, note that an installation can be safely aborted at any time by
       hitting  the  interrupt  key.   faxaddmodem delays making installation-
       related changes until after everything has been setup.


       -s speed  Communicate with the modem at a fixed speed; this may be  any
                 value recognized by the stty(1) command.

       -f        Use  the fuser(1) command for exclusive access to the device.


       faxaddmodem uses prototype configuration files that have  been  created
       for  known  modems.   These  prototype  files  are  kept  in the config
       subdirectory and, by convention, have names that identify  a  brand  or
       type  of  modem and the DTE-DCE flow control scheme the prototype files
       configures.  The faxaddmodem(8) program that is  used  to  configure  a
       modem for use with HylaFAX selects a prototype configuration file using
       information retrieved from the  modem  and  comments  embedded  in  the
       prototype  files.  For Class 1 and Class 1.0 modems the product ID code
       returned by the command ``ATI0'' and  the  response  from  the  command
       ``ATI3''  are  used to select a prototype configuration file, while for
       Class 2 modems the manufacturer and model as returned  by  ``AT+FMFR?''
       and   ``AT+FMDL?'',   respectively,   are   used  (or  ``AT+FMI?''  and
       ``AT+FMM?'' for Class 2.0 and Class 2.1 modems).

       A Class 1  prototype  configuration  file  is  identified  for  use  by
       faxaddmodem by searching for a comment of the form:
       # CONFIG:CLASS1:144:.*:RTSCTS: Manufacturer='AT&T' Model=Dataport
       In  this  example  ``144''  is the product ID code for an AT&T DataPort
       modem, ``.*'' is a regular expression matched against the result string
       returned by the ``ATI3'' command, and ``RTSCTS'' indicates the modem is
       configured to use hardware flow  control  during  fax  operation.   The
       remainder of the line is evaluated by the sh(1) and used to specify the
       modem's manufacturer and model  (since  Class  1  modems  do  not  have
       standard commands to query this information).

       Class  2,  2.0,  and 2.1 prototype configuration files match the string
       ``manufacturer-model-flowcontrol''  against  a   sh(1)   glob   pattern
       specified  in  the configuration file, where manufacturer and model are
       the strings returned by querying the modem and  flowcontrol  is  either
       ``RTSCTS''  for  hardware flow control or ``XONXOFF'' for software flow
       control.  For example:
       # CONFIG: CLASS2.0: USRobotics*-XONXOFF
       are configuration comments that appear in  the  prototype  file  for  a
       ZyXEL  1496E  with Class 2 support, and for a US Robotics Courier modem
       with Class 2.0 firmware.

       The faxaddmodem program merges server-specific configuration parameters
       into  a  prototype  configuration  according  to comments placed in the
       prototype file.  All lines between ``BEGIN-SERVER'' and  ``END-SERVER''
       comments   are   placed   with  the  appropriate  server  configuration
       parameters.   Note  that   this   means   modem-related   configuration
       parameters must be placed outside this area of the file.
