Those three lines are the relevant portion of the log that I needed to 
compare with what was happening with that modem in HylaFAX.

Notice that here you see the modem doing what it is supposed to do, 
whereas when you have it running with Linux/HylaFAX you get:

<-- AT+FTM=145
--> CONNECT
<-- data, DLE+ETX
--> NO CARRIER

So basically the modem is behaving differently in Windows than it does 
in Linux/HylaFAX.  If this is a winmodem then it can be explained 
entirely by a difference in the drivers.  However, (and otherwise) the 
problem could be in the particulars of the modem setup used by the 
application.  Here is how the Windows application initialized the modem:

AT&FS0=0E0V1Q0
ATS7=60&D3&K4
ATX4M1L0
AT+FCLASS=1
Rate: 57600

AT&F is roughly equivalent to ATZ, and HylaFAX prefers ATZ - I don't 
think there's a difference there.  HylaFAX uses ATS0=0 as well as ATE0, 
ATV1, and ATQ0.  HylaFAX also uses ATS7=60.  The ATM1L0 deals with 
speaker control and is configurable in HylaFAX and should be irrelevant 
to the matter-at-hand.  The AT&K4 indicates that the Windows app is 
using software flow control.  The AT&D3 deals with DTR handling and is 
configurable in HylaFAX and should also be irrelevant.  The session log 
that you sent shows that you had HylaFAX using software flow control.  
You may want to double-check that you have this in your modem config file:

 ModemSoftFlowCmd:   AT&K4

However, the only difference is probably the rate.  Change your 
ModemRate setting in your modem config file to this:

 ModemRate:   57600

So at this point I think that I need to take a look at your modem config 
file if things still don't work.  Please send your modem config file as 
well as the probemodem output when run against your modem.
