We're connecting an AT&T UNIX PC to a Sun 4/110. We've got uugetty on the AT&T (3.51, hardware flow control enabled, new combo PROM, HDB/BNU). We've got getty on the sun ALM-II (4-3.2_REV2, set the kernel bit to recognize carrier). The cable we're using is the standard AT&T cable: 1-1, 2-3, 3-2, 4-5, 5-4, 6&8-20, 7-7, 20-6&8 The Sun appears to announce 'nodename login:' regardless of existance of carrier. This leads to 'getty wars'. If the sun would just shut up until it gets a character (like the AT&T), these wars would not be fought. Or perhaps I need to use a different cable. Any thoughts?

I am using a straight through 10 wire cable. I also have S53=4. For the Devices file, the ",M" turns off O_NDELAY until after the first send is done in the Dialers file. For the Dialers file the "\M" turns off O_NDELAY, and after connect the "\m" turns it back on. If the "\M" is NOT the first thing sent, then O_NDELAY will not be contiguous. ----------/usr/lib/uucp/Dialers---------- tbdir tty000,M - Any tbcu wake tty000,M - Any tbwake 103 tty000,M - 300 tbdial 212 tty000,M - 1200 tbdial v22 tty000,M - 2400 tbdial pep tty000,M - 19200 tbdipep ----------------------------------------- ----------/usr/lib/uucp/Dialers---------- tbcu =W-, "" \M\K\dA\pA\pA\pT\r\c OK-\rAT\r\c-OK ATS???????????????\r\c OK ATE1\r\c tbdial =W-, "" \M\K\dA\pA\pA\pT\r\c OK-\rAT\r\c-OK ATS???????????????\r\c OK ATS66=1DT\T\r\c CONNECT-\c-CONNECT \m\c 00 tbdipep =W-, "" \M\K\dA\pA\pA\pT\r\c OK-\rAT\r\c-OK ATS???????????????\r\c OK ATSS50=255S66=1DT\T\r\c CONNECT-\c-CONNECT-\c-CONNECT \m\c FAST ----------------------------------------- John -- John Bly Milton IV, jbm@uncle.UUCP, n8emr!uncle!jbm@osu-cis.cis.ohio-state.edu (614) h:294-4823, w:764-2933; Got any good 74LS503 circuits?

My Combo card causes my system > to hang when I use tty001 or tty002, do I need a hardware patch? Yes. AT&T will send you, for free, a new PROM for your combo card. The one-line I have about the chip you SHOULD have is: 8530 chip rev J or better Zilog Z08530 This is the largest chip on the board. As long as you have Rev J or better, you're OK. Just call the hotline and say you need the free combo board chip upgrade that they're providing. They should know about this. > When HDB places a ACU call, why the *&^^% doesn't it open the port > with O_NDELAY?

The \M turns off carrier check, and \m turns it back on. This way, if rush gets a BUSY, NO CARRIER, or any other cause which hangs up, HDB stops trying. The 'Blazer nodem is set up so it drops carrier when it hangs up the phone. This has the advantage that it can detect answer failure. If I left carrier detect to truly detect carrier, it could only detect line status after a connection was made. rush would not learn when a 'BUSY' occurs, for example.

I don't know the whole story, but apparantly some of the 8530s that were used in some combo boards had some inherent defects which caused a port to lock or computer to crash when a lot of I/O was happening on the combo ports. I have the new 8530, and my board works fine with a VT100 connected to it at 9600 baud. ----- Gil Kloepfer, Jr. U-Net: {decuac,boulder,talcott,sbcs}!icus!limbic!gil ICUS Software Systems Voice: (516) 968-6860 [H] (516) 746-2350 x219 [W] P.O.

I think I forgot to mention that the fix for the Combo Boards is FREE, if you know what to tell the person on the hot line. What they do is match your symptom to their list. If your symptom(s) match the Z8530 replacement, they'll send you the kit. Now for what you asked. The problem I was having was garbled data that went from one machine to the other WITH the Combo board. I think I also mentioned crashes that seemed to be board related, but I wasn't sure about that one.
