So this very same hardware was working fine with the very same version 
of HylaFAX under FreeBSD before switching to Solaris where the problems 
started?  If so, it would seem to be either a bug in the Solaris serial 
driver or a problem in how HylaFAX handles the serial port on Solaris 
(that doesn't always cause the modem to lock up).

If you power-cycle the modem (it's external, after all) does it wake 
up?  I suspect not, which would mean that the problem is in the serial 
interfacing.

There is an unlikely possibility that the slightly different modem reset 
procedure (which only comes into play in potential wedged conditions) in 
HylaFAX+ would be able to recover modem connectivity.  You may want to 
give that a try.  Assuming that does not work you'll need to get 
debugging information out of the Solaris kernel serial driver in order 
to proceed with any predictability.

Thanks,

Lee.
