I have been very happily using my TB+ for dial-in/dial-out on a dumb 4-port Digiboard for almost a year now. Last weekend when I upgraded to 3.2, things broke. The manual says that you can use /etc/getty for bidirectional modem lines just like you could with XENIX, but that does not seem to be true. When getty is active on my tty2A device, neither cu or uucico can use the line. The error message is "CANNOT ACCESS DEVICE." I can understand this since both cu and uucico run SUID uucp and the device is owned by bin and not writable by anyone else. I also tried changing the permissions on the device, but getty changed those too. When I use uugetty on the modem line, I can dial out without difficulty. The problem is when someone tries to dial in. As soon as CD goes high, the computer drops DTR and the modem hangs up. I am using /usr/lib/uucp/uugetty -r -t 60 tty2A m for my inittab file entry. Also, I am using the dialTBIT dialer if that matters. I have tried it with and without the -r option. I would really appreciate any ideas you 3.2 gurus out there might have.

They told me if I backed off to 9600 things world work. I was also told there would be a SLS fix coming for the problem. No time frame was given though. I guess that means that all you TB+ people out there had better be ready to go to 9600 when you upgrade to UNIX 3.2. -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry

Nonsense. While I can't say that 3.2 has been without upgrade problems, I am running the TB+ at 19.2 call in/call out with no problems. I am using RTS/CTS flow control -- perhaps that's the trick. Set that register on your TB and make sure you use a cable with all the wires. -- Brad Templeton, ClariNet Communications Corp. -- Waterloo, Ontario 519/884-7473

That is interesting because I just spoke with Chris in SCO support and he claims that 19200 baud is broken no matter what you do and RTSFLOW CTSFLOW do not work correctly. Here is what happens on my machine: 1) Modem answers the phone. 2) Modem raises DCD. 3) uugetty is now able to open the port and apply the stty settings to the port. If RTSFLOW and CTSFLOW are specified in the gettydefs file, the computer promptly drops RTS, and the modem cannot send any data to the computer since the modem is waiting for an active RTS. 4) If I do not specify RTSFLOW/CTSFLOW in the gettydefs file, the computer will hold RTS high. I am really glad that it is working for you, but SCO claims that it is broken, and it is broken on my machine. I am using SCO's drivers for a DigiBoard Com/4 dumb serial card. SCO support claims there will be a support level supplement for the 19200 problem, but the RTS/CTS problem will not be fixed until 3.2.2 or so. BTW: What serial board are you using and what does your gettydefs entry look like? -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry

We run a T2500 at 19.2, very successfully, to uunet. 19.2 performance and Telebit's great reliability at that speed was the crucial procurement factor for us. BTW, on Xenix 2.3.2GT. We have a developer's agreement with SCO for Unix 3.2 and ODT, and this is the first piece of *really* bad news so far. Sigh. Rob ...uunet!csinc!rpeglar

Well, I don't have rtsflow or ctsflow set in the gettydefs line. (I do have a problem with getty where it insists that dialing in logins come in with 0 parity, which is a pain -- the istrip isn't working) Here's the gettydefs line p # EXTA HUPCL ISTRIP # EXTA CS8 SANE HUPCL TAB3 ECHOE IXANY #(Telebit 19200) login: # 3 The trick might be in my telebit registers, which are a bit different from SCO's setup. But they work with dialTBIT and uugetty.

Just fine at 19.2k Right now I have the modem connected to a standard COM1. But it also worked connected to my smart card Intellicon port, which I plan to switch it over to shortly. -- Brad Templeton, ClariNet Communications Corp. -- Waterloo, Ontario 519/884-7473
