Serious? Are you actually emulating a DMC11? I'm intrigued...
Yes.
Or rather, the terminal driver contains an implementation of the DDCMP
protocol. So it can talk to async DDCMP devices -- just as RSX did
for years. Until V10, DECnet/E only did DMC/DMR type DDCMP devices.
On a Pro, which has a USART (not UART) console port, it even speaks
sync DDCMP if you want so it can talk to a DMC or DMR (and that works,
I tested it). On other PDP-11s it will use any of the async lines and
speak async DDCMP.
