ANF10 network --> DN200 (RJE, Decnet) --> should be Ddcmp --> Re5 - HECnet

Yes, my idea as well and sync idle could probably be simulated with a 1
character sync packet (Udp?) every 10 sec. or so to determine (dead) line
timeouts.  So a certain simh standard for simulation for this should first
be defined.
Nice job for the creative programmers amongst us ...

It seems like a very simple matter to simulate it as a basic character
device, separate from the KMC pairing.  The only real question is how you
represent a sync data stream in a simullated device.  Is it just the byte
stream over a TCP connection?  That would be easy for synchronous character
mode.  If  you also want to simulate HDLC sync devices, that's a different
matter entirely; there isn't an obvious way to do that.

In other words, if someone wants this, just design how it communicates and
do the code, it doesn't sound hard.

 No, the Dup is only simulated as Kdp/Dup combo, hence the Ddcmp characteristics of
the pair.

 Fair enough.

 But DUP11 is a sync character based interface. So that one too requires that you do
DDCMP in software. But I didn't think simh simulated a DUP11?
