Hi, Im having trouble accessing my serial port since I
upgraded to XP pro. Applications give error messages such
as "Com port in use". I have no software running that I
can see that is holding the port and I have checked
startup and taskmanager processes.
The comm port is enabled in bios and shows normally in
device manager. I am having this problem with a few pcs
at the moment since our company upgraded.
I have tried writing a couple of lines in VB6 to try and
open the com port:
if mscomm1.portopen = false then
mscomm1.portopen = true
end if
When running this, I had a breakpoint on the first line,
the program would step into the second line (which
suggests the comm port is not responding as open) but on
executing the port open command would give error
message "port already open". This doesnt make sense!
Can anybody help?
