Convert a VGA PORT to become a COMM PORT
Hey all
hopefully someone can assist, I am using Harris Radios to connect to HP laptops, I require the Comm Port on the Radio to connect to the VGA Port on the laptop. The laptop has no serial port and I am led to believe the equipment has been connected via the VGA port in the past. My question is can I configure the VGA port to act as a serial port and pass raw data, if so what is the commands do I need to enter and where do I input them. Hopefully someone can help Thanks Paul

Re: Convert a VGA PORT to become a COMM PORT
I've never heard of this. If you don't have a COM port you can get a USB to COM port adapter.

Re: Convert a VGA PORT to become a COMM PORT
thx Foogoo
I know that usb to vga adapters are available, I am unsure if this can be done but would like to ask the forum if anyone has any ideas I did find online a command line to input into the Kernel which would enable serial data traffic over a vga port however I have not been able to find that information again. Can a VGA port become a Serial Port??

Re: Convert a VGA PORT to become a COMM PORT
Hi Hayes,
FooGoo is correct. In addition, the VGA port and the Serial Port are two different animals. VGA is a parallel port with only a few in/out lines. Serial has the in/out and common on 3 leads. An adaptor would probably not be found anywhere (?). FooGoo's suggestion for a PCI board would be a very easy solution. You may not find a new one but EBay or a Google search should turn up a good used one. Good Luck, Jim

Re: Convert a VGA PORT to become a COMM PORT
VGA can only be used to transmitting graphics. COM ports use different voltages, pins, and layout. I do not understand how any data equipment can be connected to a port that is routed directly to the graphics card.
You would be much better off following the advice of foogoo and getting an adapter.

Re: Convert a VGA PORT to become a COMM PORT
Hi Collins,
I'm sure that if it was really necessary an adaptor could be constructed but it would be even more complicated than a PCI card. Your advice and FooGoo's is still the best. Jim
