The sender is in control of that.  So if  the sender drops back to 2400 
bps, then so will the receiver... however, in your case your modem 
crashed before it could get there.

You'd need to restart your hsf in an etc/resetmodem script (see 'man 
wedged').

I suspect that if you just restart hsf then faxgetty will eventually 
reinitialize the modem and be fine.  Restarting hylafax there has the 
benefit of having an immediate affect.

Your hsf modem "crashed".  That's quite clear.  And if the modem 
"wedges" (i.e. faxgetty cannot reinitialize the modem), then it's 
crashed hard enough that the only thing that will recover it will be the 
hsf restart.

If faxing is important to you, then I would suggest a good fax modem... 
and not the headache that the hsf modem will give you.

Thanks,

Lee.
