Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

In my workshop I have a old laptop, Windows 7. Its not online, I mainly used it to drive a 3d printer.

I wanted to test a PicoMite based motor controller in the workshop, so fired up the old laptop. It found the serial port of the PicoMite, connected, but there's something not right. If I type, its been echoed back from the picomite, but thats all it does. CRTL C does nothing, there's no > prompt, even ENTER seams to do nothing, unless I set it up as CR & LF. If I turn on local echo, I get double characters, so this means the PicoMite is definitely returning characters as I type them. Its basically just returning whatever I type, nothing more.

If I plug it into my Win10 PC back in the office, works perfectly. CRTL C, I have a promt, edit works.

Updated Teraterm on the old laptop, no difference, checked terminal emulation VT100.

Any suggestions?

What driver are you using.
Getting characters echoed back is strange.
I thought that W7 needs some work to get it running. But I could be wring with that.
Also, the early picomites need DTR asserted. Not sure if that is still the case.

Probably worth saying exactly which Picomite firmware you're using.

And maybe what hardware (if any) between PC & Picomite. A USB something I guess.

It's almost as if Rx&Tx are shorted together.
