Hi Pierrick,

I not sure I know what you mean by the settings on the terminal server?
My IOC connects to the terminal server with this command, so it is a TCP connection on port 2001.
drvAsynIPPortConfigure("serial1", "gsets8.cars.aps.anl.gov:2001", 0, 0, 0)
I have 26 IOCs running under procServ on the machine where I ran the test. Quite a few of them are connected to terminal servers.

Thank you Mark,
Would you kindly share with me the settings on your terminal server? Since the IOC runs without problems from a terminal; since I have several soft IOCs running from procServ the same host computer on different ports; and since this IOC is the only one with a terminal server, I've reason to believe that the terminal server's settings may be the culprit.
Thank you,
Pierrick
The terminal server that I am using
