I'd like to start by thanking all the people who helped me get my
TB+ running - I was unable to reach all of you individually (sigh).
For the record, I have it running under stock uucp with 3.5 of the OS.
However, I don't take dial-ins, so that isn't too well tested (though
I did get it up and running on another 3B1 that takes only dialins -
it's just that I haven't tested it on a 3B1 that both dials in and out).
I do, however, have a question. Numerous people suggested I set
hardware flow control on the port (tty000) and gave TB+ settings for
that (i.e. s58=002). How? I don't see how to set a CTS flow control
protocol on that port (it doesn't show up as option during 'Hardware
Setup' on my system, and stty doesn't eat the 'ctscd' flag). So
I'm running with Xon/Xoff protocol (and s58=003). I'd prefer the other,
if someone can tell me how. Remember that I have 3.5, not 3.51.
Thanks!
By the way, I don't use cu or async_main, just uucp and kermit, so I
locked the interface at 19200 baud - seems to cause no problems.
Maybe someone (good, not like me) can figure out how to patch cu
and async_main to take 19200?
Thanks again.

/etc/hfc_ctL +/dev/tty000 turns it on. /etc/hfc_ctl -/dev/tty000 turns it off. This is documented for version 3.51 in The Unix System V Users Manual Volume I. It is in the addendum section in the back. There are a number of interesting things in the addendum that are easily over looked. Be sure to check it out. You could probably issue an ioctl call from a c program too. One thing to watch out for is that the port hangs if you issue the ioctl while it is active. I found out when I put an /etc/hfc_ctl in my .profile that it would always lock up the line dialing in. It doesn't seem to mind if you type it in from the shell prompt while logged in over tty000; in that case the flow control changes properly without incicent. Also note that if you enable hfc via /etc/hfc_ctl, the kernel stops doing software flow control; a pain for things that want to show you more than 24 lines of stuff, but not one screen at at time and you want to type ^S.

Therefore if you don't have /etc/hfc_ctl, you don't have the capability of doing HFC. (Sorry). stty ctscd isn't valid for the UNIX pc. For those running 3.51 (and of course if hfc_ctl appears in 3.5): To set up HFC on any tty00[0-7] port you can do the following. Place a file in /etc/daemons called: /etc/daemons/hfc_init In the file put: /etc/hfc_ctl +/dev/tty00x (where x is replaced with 0 through 7) You can put multiple lines as this is a shell script that will turn on HFC for the port specified. Note: /etc/hfc_ctl +DEVICE turns on HFC, whereas, /etc/hfc_ctl -DEVICE turns off HFC. Also set up the gettydefs file so that the lines settings doesn't have IXON for that port. One question I have for those running HFC, how do you stop the output manually? Since ^S/^Q is turned off, how do I stop 19200 baud from "Blazing" past my screen :-)? |>By the way, I don't use cu or async_main, just uucp and kermit, so I |>locked the interface at 19200 baud - seems to cause no problems. |>Maybe someone (good, not like me) can figure out how to patch cu |>and async_main to take 19200? |> I doubt sincerely that the async_main (terminal emulator) can really handle anything over 9600. It kinda slow. I know I have problems with machine<->machine connections at 9600 (ie. dropped characters). -Lenny -- Lenny Tropiano ICUS Software Systems [w] +1 (516) 582-5525 lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 {talcott,decuac,boulder,hombre,pacbell,sbcs}!icus!lenny attmail!icus!lenny ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752
