Hi Mats,

It's good to have someone with experience in non-TCP environments! Glad you're here.

The X.25 API doesn't provide the equivalent to the tcp listen(2) backlog parameter. To drive an X.25 acceptor to be capable of accepting incoming calls at a high rate, one has to implement the backlog oneself.

This is because you are doing this in the wrong place IMHO. ( see below ).

Perhaps this is something that should be part of the impl of the acceptor for X.25. That would make X.25 and TCP the same in this sense (there are no doubt other differences of which this is just one).

No. You are comparing apples and oranges. TCP is a transport layer protocol and X.25 is predominantly a Network layer protocol. A connection Oriented equivalent to IP. The correct place to do this is with a device driver 99.9% of the time. /ikh
