Sweet! Can we see some pictures? I've been looking for a videotex
terminal, but since noone remembers what videotex (or NAPLPS) is
anymore its hard to find out exactly which terminals have this support
without already knowing about it.
I've just started poking at the thing and
haven't gotten far, as I
need to grab a null modem from elsewhere,
I use a USB<->RS232 dongle (they're cheap) and talk to terminals with
my PC. I write code that generates the appropriate escape codes to
make the terminal do something interesting. You can also use a
terminal emulator program and have it talk to your terminal like its a
modem. I haven't needed any "null modem" cables in order for this to
work so far.
I have at least found an online source for the NAPLPS
encoding itself:
http://netghost.narod.ru/gff/vendspec/naplps/naplps.txt
The only reference I know of is that there was a big article on NAPLPS
in BYTE magazine back in the early 80s. I believe it was mentioned on
the cover, but I couldn't find any mention of it here
