As usual, the problem with asking for a termcap for a computer (as
opposed to a terminal) is that you need to specify what terminal
emulator you're running.

Here's a termcap that works when the TRS80 model II (or model 12 or 16)
is running CP/M from Pickles & Trout, in my opinion the best CP/M for
the II.  For a terminal emulator, all you need is a program that reads
characters from the serial port and sends them to the console, and
reads characters from the keyboard and sends them to the serial port.
It's a twenty line hack in assembler, since P&T CP/M includes
additional BIOS calls to test the status of the serial port and to do
blocking and unblocking reads and writes.

I've been using this for four years over a 1200 baud modem.  It works
great with Gosling/Unipress emacs, vi, rogue, and hack.  The only
problem I encounter is that, when doing half-screen scrolls in vnews,
there's not enough padding or vnews is ignoring the pad requirements.
At speeds higher than 1200 baud, you would need to either increase the
padding or implement some form of flow control.

The above-mentioned twenty line terminal emulator program is available
from me on request.
