Is there any way to keep XP from assigning a different com port to a USB serial port adapter? We have some programs that need Com 1 or 2 to operate. Darn com port assignment changes every reboot.

Thanks all

Is there anything useful here you can play with?

Overview of the COMDisable Tool

See if these lead anywhere?

HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports

Search the Registry for COMn (n = number) and see what else you can turn up.
 
Hi Linney,
Thank you, I'll have a look around. Now to get my boss's laptop.
