How about AT&T using RJ45 Telephone style jacks for their 3B line of computers. In theory you are supposed to be able to buy the appropriate type of DB25 adaptor for each piece RS-232 equipment you have and then just use 8 conductor cable with an RJ45 at each end. Modtap also makes a complete system using these type of adaptors. It doesn't seem compatible with AT&T's, but seems to have more variations on how you can hook things up. They define everything in terms of DTESYS/DCESYS, DTEDROP/DCEDROP, 4w/6w/8w drops. If you can figure out what each end of your cable should be, DTE/DCE, SYS/DROP, then determine which of 4w/6w/8w you need, then just order the appropriate parts. I havn't actually used either of these systems yet. I'm about to though, Bell Tech uses the AT&T version on it's ICC card for IBM PC/AT's. Anyone who has used either of these systems care to comment on their pro's and con's. Do they really work as well as advertised? -- {ihnp4!alberta!ubc-vision,uunet}!van-bc!Stuart.Lynne Vancouver,BC,604-937-7532
