Yes.

If you look in the modem manual you'll see a "busy out" option for the 
DID AT commands.  You need to use these and make sure that the modem is 
always busied out while it is resetting/reinitializing.  AND, to do this 
you need to set up the reset-state of the modem to be busied out, only 
enabling it after the reset is complete.  I've varied my approach on 
this over the past couple years, but take a look at these threads:

Here's how I have a couple of them configured:

ModemType:        Class1.0
ModemRate:        57600
ModemFlowControl:    rtscts
Class1EnableV34Cmd:    AT+F34=14,1,2
Class1TCFRecvHack:    yes
Class1TMConnectDelay:    400
ModemReadyCmds:        AT*DS1*DD0*DF1*DN4
CIDNumber:        "DTMF"
CIDNumberAnswerLength:    4
ModemResetDelay:    0
ModemSoftResetCmdDelay:    0
ModemResetCmds:        AT*DS0


With current incantations of HylaFAX CVS HEAD the Class1TCFRecvHack is 
probably unnecessary (it wasn't very necessary before, either).
