Also strange that this seems to only be a problem with BBSes that run mystic.
AFAIKT this is transmission speed issue, I am doing all this on a 286 so even in dos my terminal software struggles to keep up with everything leading to at times quite severe input lag. I think that sometimes the full ANSII escape code sequences  for up/down arrow (ESC[U & ESC[D) not being send all at once, i.e. there is a significant delay between the transmission of the ESC char and the rest which is probably confusing mystic.

Pretty much confirmed this in procomm plus for DOS. Disabling the comm sofware's status bar improved performance noticeably... and all of a sudden the arrow keys started working correctly.

I can only imagine how bad this would be on a 8088/NECV20 machine...

 AK> Thanks for the link to the IP-only setup also!

The main differences from my instructions are:
1 - Set a gateway in the Server Setup.
2 - Set connect mode to D6 in the Channel 1 Setup.
3 - Skip setting up a remote IP and port in the Channel 1 Setup.
4 - Tcpser & a server to run it on no longer required.

The rest should be the same or at least should work even if it
