The company which I work for is having trouble with an apparent incompatibility between Unipress Emacs and a Computone Intelliport serial I/O board. We are using version 2.15 of Unipress Emacs, on an ITT XTRA 386 running SCO XENIX System V, release 2.2.6, and a 16-port Computone Intelliport serial I/O board, driver version 4.28. While using Emacs, about 10 to 15 percent of the key- presses are misunderstood, with consequences ranging from irritating (you have to back up and retype something) to disasterous (a keypress is interpreted as "delete the last 15 lines or so"). We are running the ports at 38,400 baud using telephone type cable over a maximum distance of fifty feet, but this problem shows up even at just five feet from the computer, at 2400 baud! We are using Wyse 150 terminals, and the Wyse 60 termcap entries, but this doesn't seem to be the problem; if we hook one of the Wyse terminals to a conventional (non-Computone) port, the problem goes away! So, there appears to be an incompatibility between Emacs and the Computone hardware/software. I have contacted both Unipress and Computone; both companies claim no knowledge of any such problem, and neither have been able to help me with this problem. Has anyone ever had such a problem, or heard of a similiar problem? What did you do about it? Please mail responses to me (attctc!radar!eldredge), and I will post a summary to the net. If you can't reach me by mail, post an article. Thanks! John F. Eldredge, attctc!radar!eldredge or attctc!radar!parthe!jfe Programmer/analyst/system administrator, Food Marketing Services, Inc.
