Send and receive X.25 frames over regular asynchronous serial
lines such as telephone lines equipped with ordinary modems.
Experts should note that this driver doesn't currently comply with
the asynchronous HDLS framing protocols in CCITT recommendation X.25.
To compile this driver as a module, choose M here: the
module will be called x25_asy.
If unsure, say N.
