I've seen one other instance of this - which also occurred with a USR 
56K modem.  I have a patch which I'd like to test which should prevent 
the modem from hanging in the receive state.  As for the problem with 
the timeout... I don't know.  It could be one of the myriad of USR bugs 
out there, but oddly the other person who has reported this stated that 
it didn't occur when using 4.1.2.

So, maybe you could report on 4.1.2 having this problem?  Maybe you'd 
like to try my patch?

Lee.
