Highly credible sources tell me that the uugetty shipped is an obsolete one; if you get them to recompile it from source and send it to you, it'll work a lot better. I have a Telebit PC internal modem and have had no trouble getting to work as a dialin once I did this: carefully set the modem's defaults to be "normal" modem control, set the line in inittab to use the "8bpc9600" line from gettytab, except on that line delete references to PARENB and replace them with HUPCL. Then people have been able to dial in with a TB without much trouble. However, the input throughput of their asy driver is terrible. I exchange news with a nearby Sun, which doesn't win any prizes in the async department either, but I notice that when I send them stuff with uucp, using the Telebit's uucp spoofing mode, I can send to them at about 14000 CPS, but they can send to me at only about 600. I attribute this entirely to the poor input driver on /ix. I recently got a rewritten asy driver from Jim Murray (jjm%jjmhome@m2c.m2c.org) which seems to work a lot better. It also has the wonderful addition of separate incoming and outgoing special files that know about each other; that is you just spawn a getty on /dev/ttyM01, and you can uucp out on /dev/tty01 and it does reasonable things to allow only one of the processes to get the tty. This way you don't have to fool with uugetty. The new driver is also supposed to be a lot faster, but I don't yet have enough experience to say. -- John R.
