Yup, I used to do a lot of those service calls in the days before DZ11's -- I seem to remember you had to add the jumpers to enable the DL11's modem control lines. I also remenber being told that the drivers were not on all the early boards. As the chip prices dropped it made economic sense to only stock a generic M7800. A lot of CE's did the jumpers for customers on service contract for no charge on PM time. The real killer is the RP07 speed up -- change the interleave by reformatting after removing a jumper. -- Bill Pechter -- Home - 103 Governors Road, Lakewood, NJ 08701 (201)370-0709 Work -- Concurrent Computer Corp., 2 Crescent Pl, MS 172, Oceanport,NJ 07757 Phone -- (201)870-4780 Usenet . . . rutgers!pedsga!tsdiag!scr1!billp "Work didn't drive me to drink . . .
