How can I redirect Windows COM port output to a file?

Asked 2009-06-27T12:11:15.550

Is there a simple way of redirecting serial port output to a file, that I can put into place on a test Windows desktop system without changing any code?

I'm trying to debug a problem in a serial receipt printer module and I don't have the real device handy today. I don't want to start making any changes to the code if I can help it, I just want to capture what is currently being output at the moment so that I can review it in a file.

It's Windows XP, if that makes any difference.

A quick google led me to RS232 Data Logger - I haven't tried it, but if it does what it says on the tin it should be OK for you. Edit: it appears to be incoming, not outgoing. Might be worth a try though :-)

If you are developer use Serial Port component from .NET or if you don't are a developer and only want get information to file use windows HyperTerminal

I don't know if you can redirect COM ports but you can use com0com for that kind of job.

For example, you can pair (COM1, COM2), so you can write to COM1 and read from COM2.
