• Subject: Async comm not timing out

Hello again!

This week's question is for the communications programmers.
I have an async program that does an invite, then a read.
The WAITRCD is set to 15 seconds, and works most of the 
time.  The situation where it doesn't work is when I 
have lots of parity errors on the line.  What happens is...
nothing.  The line, controller and device all show ACTIVE
but the READ doesn't time out.  If I cancel the job, the
controller and device go to FAILED.  If I vary the line, 
ect. off and on and re-start the job, everything works fine 
until the parity errors pile up again.

Has anyone else experienced this?  Any ideas for a solution?
It happens on V2, V3 and V4, so it's not a PTF issue, nor is
it a RISC/CISC issue.
