[hylafax-users] DID problem

[David Brodbeck <DavidB@xxxxxxxxxxxxxxxxxxx>]

I'm having some problems getting DID to work.  I'm using a MultiTech
MultiModemDID, and Hylafax 4.1.1-3.1 (From Debian Woody).

Reception on the POTS port of the modem works fine, but not on the DID port.
The modem gets the DID digits okay, but then things just time out:

Feb  7 12:25:02 dialtone FaxQueuer[277]: MODEM ttyS0: READY, capabilities
P3fc3e7ff:ff
Feb  7 12:25:15 dialtone FaxGetty[399]: STATE CHANGE: RUNNING -> LISTENING
Feb  7 12:25:15 dialtone FaxGetty[399]: MODEM input buffering enabled
Feb  7 12:25:15 dialtone FaxQueuer[277]: MODEM ttyS0: BUSY
Feb  7 12:25:15 dialtone FaxGetty[399]: --> [5:DTMF4]
Feb  7 12:25:15 dialtone FaxGetty[399]: --> [5:DTMF7]
Feb  7 12:25:15 dialtone FaxGetty[399]: --> [5:DTMF5]
Feb  7 12:25:15 dialtone FaxGetty[399]: --> [5:DTMF2]
Feb  7 12:25:20 dialtone FaxGetty[399]: MODEM TIMEOUT: reading line from
modem
Feb  7 12:25:20 dialtone FaxGetty[399]: <-- [5:ATH0\r]
Feb  7 12:25:21 dialtone FaxGetty[399]: --> [2:OK]

The problem appears to be that, during configuration, HylaFax is setting
S-register S0 to 0, which means it needs to issue an ATA before the modem
will connect.  But when it's received the four DTMF digits, it never issues
the ATA -- it times out and hangs up instead.

Here's the config file I'm using:
