Well, what I would like to see is a new "x25.device" device that could be put in the devs: directory then just used on any program that allows devides other than serial port... Like I could set my BBS up just by telling it to use x25.device then unit 0 for line 1, unit 1 for line 2, etc... Hmmmm, I bought SAS/C a few days ago, maybe once I learn enough this might be a project I'd look into doing... -- .____________________________________________________________________________. | | | | Please send all | Sysop of the Virtual Reality BBS | | complaints to | uunet.uu.net!umich!vela!sycom!vrtwo!matt | | | 808-337-1560 * 2400 baud * C-Net Amiga | | >NIL: | USR 14400 baud DS on order - 40 megs storage | |__________________________|_________________________________________________|
