It's also nicely encapsulated in the xtoc source, available on the ftp
site (ftp.biostat.washington.edu). It's a surprisingly simple protocol,
and whoever designed it was definitely a unix weenie (there are commands
like LS, MV, CP, etc.)
Most of the commands are two-character strings preceded by an escape
The basic commands themselves are:
The returning data streams for most of the commands use semicolons as line
Most of the commands (except for XF) can be tested using any communications

means that filenames containing an exclamation point cannot be transferred

Zoomer will *not* scroll the screen. This is good, since otherwise the
comm program on the PC would probably assume a timeout condition. Other
commands, however, *will* scroll the screen if any output occurs at the

ottom of the screen, so I've found it works well to append a "cl" command
immediately after each command (eg, "\033LS\033clReady...") to avoid timeouts
on subsequent commands.

clean it up and comment it), or check out the source to xtoc.
