Noflow parameter and ZeroWindow message


We are having problems with two “Digi One Ts8”, they are receiving rs232 data(9600pbs) from port 1, We use rtelnet to obtain that data from a Solaris 8 Machine.

Sometimes we have problems with the conecction between the solaris Machine an Digi and we saw in a network analyzer (Ethereal) ZeroWindow Message reported by the Digi.

We saw some stats from digi and saw that in “info serial” there are a lot of “noflow” Failures (It can be a real problem? What is the Received Buffer?)

It sounds like the flow control set on the Digi serial port might not match that set on the Solaris 8 consoled server. Check/compare the flow control on those two and make sure they match.
