1. How do you escape # in order to write a C program
if # is the erase
character in the terminal?
"Use the source, Luke!" V7 is simple enough that it's pretty quick to find
the answers to things like this. E.g.
http://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/sys/dev/tty.c>
will answer this question (in "canon()").
3. Is there a way to echo the ascii value of a
keypress in v7?
A quick look through tty.c suggests this doesn't exist in V7 - without running
a user program that puts the TTY in 'raw' mode and prints out what it
sees. Not sure if there is one off the rack, or if you'd have to whip up a
20-line program to do it.

Duh! I see it now... backslash. All that cooked and raw stuff is
gobbledegook that I'll have to read up on.
Maybe later :).

Works great on my macbook, not valid in V7, but that's ok, now at least
I know what key value is being sent (0x7f).
Thanks,

I never claimed that it was portable :-) Going by the date, I'd say it
was written for a CCI Power-6/32 (sorta SysV-ish) with some odd terminals
that I had to incorporate into TERMINFO for our office software; I dimly
recall posting it to aus.sources in case others could use it.
