Hello: Does anyone out there know how to, either 1) Do intelligent baud switching with getty or 2) Send a BREAK from uucp? The machine is a 7300 UNIX PC with a P5 motherboard and 3.51 software. The docs and internal uucp documentation on this subject is non-existant (Either that or it's referenced in such a way that I can't find it). And yes I have had a lot of experience with other uucp combo's inc HDB uucp. Anything I've tried from the backslash include characters to the word BREAK on the control line fails at this level. Any response is greatly appreciated and will be returned in kind if I have info that you need. Thank-you. -- John Grzesiak --

If I don't remember clearly anymore, I'm sure someone will correct me (many times :-). Anyways, stock 3.51 has a semi-broken serial driver which prevents BREAKs from being correctly transmitted (i.e., at all). While you're probably doing everything correctly, the BREAK is just not going anywhere. The resolution to this is to obtain Fixdisk 1.0 from the hotline (also affectionately known as 3.51a around here...) -- ________Robert J.

I have been unable to reach the author for some time, but the notices make me think I can redistribute the source. It requires a verbose modem, which will tell it what baud rate to switch to. Prtty takes care of the rest. It also makes the line useable in both directions, since it can detect unsolicited traffic on the line and go away until the line is no longer in use. These switchovers take a little time, but they have been very reliable on my machine. I have been using this for some time, with HDB and a telebit. Without prtty, I had no end of trouble with the 'blazer. With it, I have been without a glitch for a very long time.
