Using screen, and executing a ST macro from Rivendell, I see an output of

Does it produce the correct result, though?
It would appear then that the Rivendell "driver"
for the Broadcast Tools 8x2 speaks a slightly different language than
what my 8x2 actually understands.
As far as I know, 8x2s have always understood the same language.
Is Rivendell defining the serial port with different parameters than
minicom? Is Rivendell running as a different user than minicom? If so,
does that user have sufficient privileges to use the serial port?
In Wayne's documentation, you can execute commands to the serial port via
rmlsend with some shell scripts with screen commands. I'm sure I can make
that work, but is there a way to make a "driver" for Rivendell like the
existing Broadcast Tools 8x2 switcher one?
UTSL ("Use the source, Luke").
Personally, I wouldn't bother, though; I'd have Rivendell run a
constellation of shell commands containing whatever language you need to
make the switcher work.
