8155Recover Serial Port
- Aug 22, 2008To All,
This is way off topic, but someone here may have a quick answer to my
question: how can I recover the use of a serial com port that was being used
by an application on my PC when I want to switch to another application that
needs that same com port?
I want to control the slewing of a telescope by using a dedicated stand-alone
PC. Sometimes I will use program A to do it, and other times I will use
program B to do it. Currently, the only way I know of to permit program B to
access Com 1 after program A has been in use is to exit program A and reboot.
I can also use Device Manager to remove Com 1, but that still requires a
reboot in order to regain access to Com 1.
Can anyone tell me of a way to free up Com 1 after the first application
exits? I think a DOS command exists for this purpose, but I didn't find it. I
also looked at MSCONFIG, but no joy.
I'm using WinXP Pro SP3.
Thanks for the help.
