Error conflict communication port

6
hi all, Help me
My PC is connected to a Olivetti printer through COMM1 port and I installed driver for the printer, but
after do this, i can not program to open comm port in C#. The Error display: The given port name does not start with COM/com or does not resolve to a valid serial port

Thanks,
All the best

Does your printer have some other software using the port?

I get that message on my windows7 machine frequently. What I do to get around it is to open the Device Manager, delete the offending serial port, and then do a couple of Scan For Hardware Changes. That brings the serial port back and then I can use it just fine.

Ahh yes, everytime I restart the computer my COM port is messed up. I perform those actions but not reboot.

Leave the driver intact, remove the com port from the hardware section (NOT the software section) and then let it "scan" so it finds the com port again

Go to the hardware manager section and go to the serial port. Then right click and choose install.
