communications with plc

[cmon3c]

I am a new user with a plc in general.  With that said I have figured out how to get around fairly well with monitoring a program while in service.  I have had a few customers that I have problems communicating with , so I called A>D> tech support.  I was told that it sounded like noise was my problem, and i needed to go to the task manager and disable my comserv, because it was my pc that was stopping my communication.  Can someone help with this.  It causes my computer to lock up and I can re-bbot and communicate generally for a few minutes before it locks up again.  frustrating!!!!!!

cmon3c, I work closely with AD techs. If they said it sounded like noise was your problem, have you taken the precautions or preventive measures they recommended? Also, what Win OS are you running? Are you using a USB-to-serial adapter? Or...?

WINDOWS XP   USB-SERIAL ADAPTER---JUST WASN'T SURE WHAT I NEEDED TO DISABLE IN MY TASK MANAGER.

You usually don't have to disable anything using Task Mugger.

Are you using Automation Direct's USB-to-Serial adapter? Here is an FAQ on USB-to-serial adapters with DirectSOFT:
