Help getting efax to receive?

["Kevin Beauchamp" <Kevin.Beauchamp@ualberta.ca>]

Hello:

I'm not sure if this is the right forum for this type of question. If not,
I apologize.

I'm just starting with Debian and want to use it to run a fax and print
service in our location on a P90 machine with Debian 2.2r3
loaded. I've loaded efax 0.9-4 from the Debian web site (I couldn't
find it on the CDs I have) and configured it to run and attach to
/dev/ttyS1. I can get efax to send faxes and print TIFF files, but
not receive faxes.

I've tried two modems (USR Sportster, USR Courier)
and have gotten slightly different results. In both cases,
efax will answer the incoming call, and will successfully
retrieve the originating fax's ID and phone number, but
the session fails when it tries to receive the document.

Here's a snippet of a session log with the Sportster (Type 1 fax):

  efax: 23:00 received DCS - session format
  efax: 23:00 session  98lpi  9600bps 8.5"/215mm  any   1D    -     -  0ms
  efax: 23:00 command  "+FTS=1"
  efax: 23:00 waiting 3.0 s
  efax: 23:00 .798 [<CR><LF>OK<CR><LF>]
  efax: 23:00 response "OK"
  efax: 23:00 command  "+FRM=96"
  efax: 23:00 waiting 6.0 s
  efax: 23:01 .098 [<CR><LF>CONNECT<CR><LF>]
  efax: 23:01 response "CONNECT"
  efax: 23:01 waiting 2.0 s
  efax: 23:01 .148 [<CR><LF>NO CARRIER<CR><LF>]
  efax: 23:01 response "NO CARRIER"
  efax: 23:01 received TCF - channel check (not OK: run of 0 in 57)

And here's a piece of the log using the Courier (Type 2 fax):

  efax: 11:25 session  98lpi  9600bps 8.5"/215mm  any   1D    -     -  0ms
  efax: 11:25 command  "+FDR"
  efax: 11:25 waiting 60.0 s
  efax: 11:27 .858 [<CR><LF>+FCS:0,3,0,2,0,0,0,0<CR><LF>]
  efax: 11:29 .598 [<CR><LF>CONNECT<CR><LF>]
  efax: 11:29 response "CONNECT"
  efax: 11:29 session  98lpi  9600bps 8.5"/215mm  any   1D    -     -  0ms

  [- snip: long error line -]

  efax: 12:09 Warning: 113 reception errors
  efax: 12:09 received 113 lines, 113 errors

I've read the man page, checked out the script, visited the
web page and sent email to efax's author. The author suggested
trying manual receive (same results) and checking to make sure
that all programs accessing the serial port use the same files
for locking (I'm pretty sure efax is the only one accessing the
serial port: mouse is the only other serial peripheral I know of,
and its on its own PS/2-style port).

At this point I'm fairly certain that efax is set up basically correctly,
but I'm not sure about what else may or may not be trying to lock the
serial port, or how I can test my modem(s) to make sure they're
properly configured.

One web page (the Fax-Server mini-HOWTO) mentions a fax test
script, but trying the command it suggests isn't recognized on my system.

Can anyone suggest a solution, or have any experience with
this type of application?

TIA
Kevin B.
