This old workhorse, lsuc, is generally a fine machine for our needs. It's a Perkin-Elmer 3220 running "Edition VII Workbench", which is v7 with a few extras from BSD. Its one wart, and one that's now starting to bother me severely, is that it can't grok characters arriving at >1200 bps. For output, it's fine; I read netnews at 19200 and it's noticeably twice as fast as 9600. But on input, whether uucp on a phone line, uucp on a direct connection, data from our PADs, or even function keys on a high-speed terminal which send multi-char sequences, it loses chars randomly and unpredictably. I asked P-E about it once long ago (we have source, so we don't have software support) and was told it's a bug in the terminal driver. As our UUCP and netnews connections grow, it becomes harder and harder to do everything at 1200 baud. I'd get a Telebit if we could use it. 1 in + 3 out newsfeeds, plus about 40 regular uucp mail connections, keep our 1200 baud modems (5 of them) humming. Does anyone have any suggestions as to how I track down and fix this bug, if indeed it's in the terminal driver. I have some familiarity with the terminal driver, but not in debugging this kind of problem. Any pointers to the likely culprit would be appreciated. If the expertise required is the type of black art which can't be explained, we'd be willing to pay someone to fix the bug.
