I believe that the Selectric came configured for remote operation, but presumably using
an EBCDIC-based data stream. I vaguely recall a DB-50 connector, but it's been an
awfully long time ...
Does this description sound familiar to anyone?
For a while, RSTS/E supported 2741 terminals, which are Selectric terminals with a UART
interface. It wasn't EBCDIC -- instead, it had one of several possible conversion
tables. I forgot the number of bits per character. Also, the speed used was peculiar:
134.5 bits per second. 2741 support was dropped at some point; I think V7 has it but it
disappeared by V9 if not sooner.
