qemu virtual serial port emulation on windows

@All

Is there anyone who tried to setup real (but virtual) serial port when use qemu ? I just tried to use com0com which create for me virtual com4/com5 ports, but when i simple do for qemu "-serial COM4" and then putty on com5, i can see that things start to throws on com port, through slower than expected, and after a while simple freezes.

Is there better alternatives or maybe i do something wrong ?

The point is to have EXACTLY com port after i run qemu to which i can connect via putty/scripts to acts with it as i act with real serial port.

Thanks!

I don't know Windows but in QEMU you can define -chardev options I think and connect serial to those so you could redirect serial port not only to stdio or file but also to tcp port or whatever else so maybe you could interact with one of those in your scripts rather than making a virtual serial port.

@Balaton
Yeah, with virtual coms it was pain to make it works (i were only able to redirect output from one com to another, but once i start interract with like keypresses then everything freezes).

So i simple go :



and rewrite scripts to use TCP instead of com, so it works too.
