New subject: KG11 emulation probably defective -->diagnostic ZKGAB0 for KG11 runs without complaints. --> Crc on Rsx11 async lines

By the way, Johnny, was KG11 also used on serial async Decnet11MP lines or
was that always software?

I agree that it would be nice to confirm that this works in real hardware,
but I also find it unlikely that it wouldn't.
While DEC was not perfect, I would expect that they actually had tested this
before releasing the software.

  @Dave:

 It would only be worth the time and energy to prove if current 
 Decnet11MP in combination with KG11 would work in a Dup to Dup or Dmc 
 connection, which in hardware take a serious effort.
 In virtual reality it is far more easy to arrange such things.
 Unless I cannot find a bug quickly enough, then it could be helpful to 
 request you to check on it.

 Thanks though for the time being.

 We really don't know how robust the diagnostic is and if it exercises 
 the same details that are used by the DDCMP implementation.

 You could run the DDCMP case with KG11 debugging enabled and identify 
 what  it is doing precisely and then go back and see if the diagnostic is 
 doing the same stuff...

     I have a KG11-A board; if it would be helpful, I can install it in 
 a
 PDP-11 at LSSM perhaps this week.
