I'm trying to hook up a Telebit Trailblazer+ to a HP9000/370 via a 98642 mux (port 0). This is the 25-pin port on the '42. The problem is that I cannot seem to get the modem and the system to agree on how hardware handshaking should work. The modem seems to work ok at LOW (cough,sputter) speed using XON/XOFF, but that is unacceptable for high-speed transmissions. I have a pair of the TB's, and a pair of phone lines, so testing isn't a problem... The configuration that I've come up with so far is: E0 F1 M1 Q0 T V1 X0 S07=070 Wait For Carrier Time S09=006 Carrier Detect Time S47=004 DSR Delay Time S48=001 Eight Bit Comparison S50=000 Transmission Mode S51=254 Interface Speed S52=002 DTR Interpretation S53=000 DCD and DSR Interpretation S58=001 Flow Control Used By DTE (System) S60=000 Data Format S66=000 Lock Interface Speed S67=000 CTS Interpretation S68=255 Flow Control Used By DCE (Modem) S92=001 Answering Sequence Selection S110=255 Data Compression Enable I need to know: a) How do I configure the modem? Regs 52, 53, 58, 67, and 68 will have to be configured, but what values? b) How are the /dev's created under hp-ux 6.2, ie, what bits do you set with the mknod? c) Any special tricks with cables? d) How about using the 9-port builtin 98644 in the main system cabnet? Any problems there? e) Is there a difference in the configuration between dialing out from the modem and answering in? Thanks in advance...
