I always used 7bit IO for terminals in that era.  The base ASCII charset was 
0-127 and bit 7 was often used by many programs to signal a format effector
or binary data.  Some software actually translated the chars with bit 7 set
a set of control characters and reverse screen characters.  The driver I used
for my VDM-1 did that (reverse or cursor required bit 7 to be set).

As a consequence all of my terminal drivers then and now for the 8bit world
(Altair basic and CP/M etal) mask bit 7 to Zero on recieve.  If I needed a 
8bit terminal IO I'd then use IObyte to select a different driver that 
didn't mask.
