Thank you! This is so cool, I want to get decnet running on my pdt11/150 and connect it
to my rsx11 system.
I wonder if it can support sync serial options so I can run it at 19200 baud on the
"modem" port on the pdt.
Is the PDT port a USART? In any case you could treat it as a UART and do DDCMP over that,
it works fine (DDCMP handles either sync or async serial lines, and even other stuff like
the PCL-11 if you happen to have one).
The Pro modem port is definitely a USART, and I have used it in both modes. Unfortunately
it has a tiny FIFO.
