How do you redirect a serial port to output out of the parallel port?

Answer 1

You don't. If you are wanting to plug something into the serial port, and it is the same size as the parallel port (it isn't a parallel port, it's a different plug for the serial), use an adaptor.

I'm in the same problem. I have a laptop and a program that uses com1 and need to redirect serial communication (com1) to a parallel port since the laptop doesn't have a serial port. i have an adapter for parallel to serial connections but need to remap com1.

your can redirect lpt1 outputs with mode lpt1=com1 but not the other way round. If the laptop has usb just grab a USB to Serial Adaptor.

Am in the same boot. A Point of Sales app need to be connected via a com port for Receipt Printing... The Printer is a ESC/POS Printer but has a Parallel Connection... Works fine under Windows, but not in the POS App. What is needed is some sort of Virtual COM Port to Capture the Outputs and Redirect it the a Physical LPT Port. In doesn't sound hard, yet no ones don't it...

Answer 2

A serial port is a totally different electrical device thus, as far as I know, can not be converted to a parallel port due to differences in protocols and baud rates/data rates on the port.

You can however get a USB to serial/parallel adapter which many people have had good luck with.

Hope this helps!
