[fa.info-cpm] PIP and Keyboard Character Redefinition

C70:info-cpm (07/29/82)

I have CP/M running on an Apple with a BIT3 80-column board.  I have a boot
disk with MODEM on it.  The keyboard characters are redefined as follows:

ctl-k: "at" sign (I can't type this because it is the Multics line kill)
ctl-u: underscore
ctl-b: backslash
ctl-n: ^ ("hat" or uparrow, ascii 94)

Everything works fine up until the time I escape out of MODEM
with a ctl-e and do a PIP PUN:=B:FOO to transfer an ascii file down the
wire.  After a MODEM T to get back in terminal mode, I discover that:

ctl-k is now the Apple CP/M default of left square bracket
ctl-u is still underscore
ctl-b is still backslash
ctl-n is ^, but only if you hit it twice.

Most confusing.  Is this something that PIP has done, or is there something
wierd going on between PIP, the MicroModem, Multics, and the BIT3?  Anybody 
have a fix?
