SUMMARY
=======

The following information describes the process Microsoft At Work PC Fax uses to
initialize Class 1 and Class 2 fax modems. This information is useful for
troubleshooting initialization problems--the commands below can be sent to the
fax modem using Windows Terminal to determine exactly where initialization
fails.

MORE INFORMATION
================

1. Any command that is specified on the SetupCommand= entry in the EFAXPUMP.INI
  file is executed.

2. The following commands are sent to the modem:

  AT&F   - Resets the modem to factory defaults
  E0     - Turns echo off
  V1     - Causes verbose responses
  Q0     - Puts the modem in quiet mode
  &C1    - Keeps DSR asserted
  &D3    - Tells the modem to reset on DTR
  &D2    - Has same affect as &D3 on modems that do not support &D3
  S0=0   - Turns AutoAnswer off
  S7=255 - Sets the training time-out to 255 seconds
  S8=    - Pause time for commas in Dial string, then either X4
           (recognize busy/dial tone) or X0 (for blind dial)
  \Q1    - XON/XOFF for Microcom and compatible modems
  &K4    - Hayes-compatible XON/XOFF command
  \J0    - Microcom command for do not send DTE/DCE (megahertz modems
           recognize this command also)
  &E5    - Multitech XON/XOFF command
  *F2    - Bidirectional XON/XOFF flow control

3. The Setup command is run again and issues an AT+FCLASS=1 or AT+FCLASS=2
  (depending on the modem class) and either answers the phone or picks it up to
  dial.
