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

Maybe later :).
