Diffs against  KA9Q  S930104  -source set for creating OH1MQK [mea@utu.fi]
features -- and his DDLC card driver, and new encoding type ("HDLC")...

Files   ddlc.c, ddlc.h, ddlcvec.s, ddlc.txt, ddlc.doc, ddlctest.c, rawhdlc.c
and rawhdlc.h  are provided separately.  (ddlcpack.lzh)

Phil had made (in display.c) the query of actual screen size, and thus there
is no longer need for OH1MQK mod for it -- in stdio.c...
(Try with DOS 4/5:  MODE CON LINES=50, and then start NET)

Rundown:
    config.h:	Added DDLC-, and RAWHDLC-options, turned this & that on..
    config.c:	Added DDLC and RAWHDLC -drivers, and couple of *_helper()-
		routines. ( attach_helper(), start_helper(), stop_helper() )
    commands.h:	Added DDLC and RAWHDLC related commans.
    cmdparse.c:	Added new feature into  cmdparse() -routine: it can call up
		*_helper() -routines if needed.
    netuser.c:	Corrected IP-number parsing to conform usual Internet style:
		  127.1 == 127.0.0.1, NOT 127.1.0.0 !
