I've done some playing around with KEGS on one of my Linux boxen lately.
I had my GS's hard drive hooked up to it for a bit, so all of the apps that
are installed on it (including ProTERM) are available to KEGS.
KEGS is supposed to emulate a modem so that something like ATDTlocalhost
will open a telnet session on the host side. I've gotten that working:
tcpserver 127.0.0.1 23 /usr/sbin/in.telnetd
as root puts up a telnet daemon for local access as long as you need it.
I've gotten ProTERM to connect to it, and I can list files on the host
system. It's 1989 all over again. :-)
What's not yet working is file transfer. I have lrzsz installed, but when I
try something like "sz foo.txt," ProTERM doesn't start downloading
automatically like it should. Starting the download manually goes nowhere.
XMODEM doesn't work any better...it just times out.
Am I doing something wrong here? I'm going to need an Apple II (real or
emulated) running soon to write the firmware for the new beer-fridge
controller I'm working on (to no longer run it on an Apple II, but it is
6502-based). I figured emulation would keep everything I need in one box
that's already set up, but if I need to unpack and set up my IIGS, I can do
that.
