I have a application which opens the port using .NET 2 serial port handler.
On my computer using WinXP Pro SP2 updated I have three accounts. On two
of the accounts the program is able to open COM1 correctly but on the third
account it says the access is denied, I can open other serial ports. I have
also tried an older application I have that uses the more direct API to
access the port. This is driving me nuts...
Anybody aware of how to give myself permission on the third account. I am
set a admin on all three. The only thing I can think of is the third
account was created recently.
Thanks,
John
