So you need two serial ports for this to work.

This is really testing my memory, but I thought I saw that there was a variant of ZMP that was specifically intended for "dial in" operation. This would mean that it would be launched from and use the console port. It would not require the second serial port.

Have you seen such a thing? I may go looking for it later. I assumed it used the same overlay structure, so would be easy to adapt your current work.

Thanks,
