    I've written an application program hosted on a SUN SPARC STATION 
which dials out to remote sites using TELEBIT T2500 modems thru the 
CISCO terminal server using TCP-IP sockets.   As soon as we dial out, 
some of the modems normally start receiving large amounts of data 
even though its not being read by the application program. 
After completing dial-out, we have to wait a variable amount of time
to connect passively to a remote host, then start reading and writing 
to the modems using the NOTIFIER on the SUN.  

    If I only have to wait a few minutes before starting
to read and write from the modems everything is fine. When
I have to wait over 10 minutes, I seem to be able to read
data, but when I write to one of the ports that have been 
receiving large amounts of unread data, I get a broken pipe
signal.

    Any ideas, or solutions?

    Thanks in advance.
