Serial Port Bridging Emulator

I'm working to improve a test program for the hardware I use to test some b oards I make. These boards are tested using a test fixture controlled over an RS-232 port from the PC. So I don't need to lug hardware around with m e I emulate the test fixture on the same PC I run the test program. I need comm port emulation software that will emulate a bridge between two serial ports to connect the test program and the test fixture emulator.

One I've been using is called, oddly enough, "Free Virtual Serial Ports". It is free to use, but only in a limited configuration which will do the jo b, but just barely. I have also noticed that if my programs are not closed properly (or some other cause) this bridge software will hang one of the p orts.

I don't want to emulate the serial port connection in my test fixture emula tor because if I take the program down a lot while testing, I will have to continually restart both the test program and the emulator program. There are a few initialization steps that become tedious after doing them a few d ozen times.

Is there serial port bridge software that works well and is not expensive?

Get a Ras Pi and use a real port connection and perform real tests.

Yes.

So I need to use serial port hardware to connect Windows COM1 to a tty serial port in Linux, tie that port to a second Linux tty serial port which then connects by hardware to COM2 in Windows.

Yep, sounds pretty good. So do I run Windows in a VM under Linux or run Linux in a VM under Windows?

Any way you like. PTY (Pseudo-TTY) devices have been around in *nix since the 1980s. The world has mostly moved on, but we still have many hostages to rescue.

Thanks, that seems like a possibility. It's roots in Unix seem to make it a bit harder to understand than I was hoping for but I might give it a try when I get back to this later in the weeks.

Someone in another group suggested com0com which I now recall from doing si milar work some years ago on a desktop. I downloaded it and it seems to wo rk ok. Rick C.

Do you?

Details you should have mentioned at the start.
