I am using SDK comm  calls to access the serial ports
with XON/XOFF enabled. I get into a deadlock situation
when the sender transmits an XOFF to me and then hangs. I have
no control on the sender so it is up to my application to
time out and recover from the XOFF. What I though I could do 
is to detect XOFF using COMMSTAT bits and then 
close and reopen the port.
This doesn't seem to me like a good solution. Is there
any way to force serial driver to start accepting
data without reopening the port or receiving XON?

I greatly appreciate your help.
Please forward your answer to bahman@mdd.comm.mot.com
I will post the suggested solutions in couple of day.

Thanks,
