Access IRIS from PC problem

[Naiming Shen]

I use my  PC as a terminal to access the IRIS workstation through
a null modem cable to connect both serial ports. The software I use
on PC is procomm plus. When I try to logon to IRIS within procomm,
I get strange characters in first 2-3 minutes(if I keep hitting Enter).
then suddenly the "IRIS Login" prompt comes out. After that the PC terminal
works fine within the day(even I get off then get on procomm again).
I'm wondering if there is a sleep function built in the serial communication
on IRIS? if this is true, why should it be there?
