[HECnet] SC-40

[Peter Lothberg]

I saw 7 bit mark and 7 even back in my old Field Service days in the 80s...

Start with just 7 bits no parity. Try both one and two stop bits. Then mo=

7 bits no parity is something I=E2=80=99ve never seen.   I would start with =
8 bits no parity, one stop bit unless it=E2=80=99s 110 bps.   7 bits with pa=
rity, that does come up on a few occasions.   But while I=E2=80=99ve seen 8 =
and 5 and even 6 bit serial comms used, I can=E2=80=99t think of any 7 bits=
in the wild.

The SC40 expects a serial byte with values 0..127 (8 bits, MSB always
=0) no parity one stop bit.
