From: Jim moore <MOORE.LOSANGEL%ibm-sj.csnet@csnet-relay.arpa> I have a PERSISTENT problem using my 630 at 1200 baud (serial) on my K-10. The symptom is that when the K-10 sends more than a buffer-full to the 630, the handshake is fumbled and EVERY TIME a single character is dropped. What is particularly strange, is that the same 630 works fine with my K-2 and K-4, as well as Osborne and even Northstar (on the same test file)! My local dealer and even Kaypro themselves seem to be at a loss to explain or fix this problem. Kaypro seems to believe that I am the only person who is having this problem. Am I? To their credit, they seem to be really trying to fix the problem -- they replaced the main boards free in both my K-10s -- unfortunately, the issue remains. Is there anyone out there who has both a Kaypro-10 and a Diablo 630? Do they interface properly at 1200 baud and more than one 630-buffer load? If so, what version ROM (the first number you see when it cold boots) and CP/M do you have? If not, what have you tried to fix it and did it work? Note, this problem is NOT related to any particular piece of software; it is evidenced by "type testfile.630 <ctl-P><CR>". HELP! Thanks for anything ... Jim Moore (MOORE.LOSANGEL@IBM)
