Someone who has done work on this stuff should be able to know.
In for example Sunlink X.25, the X.25 module is done in layers.
In the configuration file, one typical command is

        iflayer $X25line $HDLCline $port

Does anyone want to guesstimate the possibility of changing this to
(lets say)

        iflayer $X25line $HDLCstartstopline $ttyline

and writing an inbetween "HDLC start/stop stream module"?
Would we then have an async-X25 connection for SUN with compatibility with
other software, or are other magic tricks required?
Would this be a man-month or a man-year project?
Inquiring minds want to know (and to have cheap X.25 this year.....)
