This seems to indicate that it has trouble re-initializing the modem on 
the first attempt, but when faxgetty respawns it is able to initialize 
it then.

That, then, suggests to me that DTR is not being handled appropriately.

Watch the modem's LED lights.  When faxgetty is running and the modem is 
initialized and idle you should see the "TR" light on.  When using 
faxgetty that light should stay on always except for when modem 
reinitialization takes place, at which point it should go off for a very 
brief moment.

So for example as faxgetty receives a fax it will be on, and when the 
fax is entirely received and the sender disconnects the "TR" light 
should go off (because HylaFAX tells the system to do that - to reset 
the modem) for a very short period of time, after which it will come 
back up.

When sending a fax the TR light should blink off (very short) as 
faxgetty hands the modem over to faxsend.  When faxsend finishes the TR 
light should go off and stay off until faxgetty notices that faxsend is 
done and then goes to reinitialize the modem (at which point it will 
come back on).

Please make sure that your TR light behaves as I have described.  If it 
does not, then there may be some code work to be done in 
faxd/ModemServer.c++ ModemServer::setDTR for your platform.

If your TR light does behave as described, then it's possible that 
you're probably looking at a modem misconfiguration.  You should have:

 ModemSetupDTRCmd:       AT&D3

in your modem config file.  That tells the modem that when the DTR is 
dropped that it should reset the modem.

Make sure that you do not have any other programs running that use the 
modem.

You may also want to try increasing ModemDTRDropDelay.  Normally 75 ms 
is plenty for the ModemSetupDTRCmd to take effect, but maybe try 
something like 1000 ms.
