I just posted an inquiry about implementations sending other than
"space parity" on Telnet.  By this, I meant "cases where the normal
Ascii data stream (not IAC, etc.) may have bit 8 set", i.e. which
ptty drivers are *calculating* and sending parity.

My motivation: In the PC/TCP Telnet (inherited from PC/IP), there
are a number of places where the 8th bit is carefully masked off
lest it make it to the display (and turn Ascii into a PC graphics
character).  I wish to know which implementations this defends against.
