Using a Telebit T2500 with a Sun 3/180 (while retaining your sanity) Our Configuration: A Sun 3/180 running SunOS 4.0.3, and the T2500 on "ttyb" (ttyd1/cua1). When our department bought a T2500, I thought that such an advanced modem must be a snap to configure, right? Well, yes and no. It was to be attached to a Sun 3/180 for both UUCP and remote logins. I worked with it for a while, and soon was able to get successful connections at up to 2400 bps, but if I tried V.32 or PEP, uucico would abort after a string of "alarm" errors. After some fiddling and calling up support numbers, I (finally) came up with this configuration: Configuration A (UUCP & Dialup) E0 F1 M1 Q4 P V1 W0 X1 Y0 &P0 &T4 Version GA2.00 S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07:080 S08=002 S09=006 S10=007 S11=070 S12=050 S18=000 S25=005 S26=000 S38:020 S41=000 S45=000 S47=004 S48=000 S49=000 S50:254 S51:254 S52:002 S54:003 S55:003 S56=017 S57=019 S58:000 S59=000 S60=000 S61:001 S62=003 S63=001 S64:001 S65=000 S66=000 S67=000 S68=255 S69=000 S90=000 S91=000 S92:001 S93=008 S94=001 S95=000 S96=001 S100=000 S101=000 S102=000 S104=000 S105=001 S110=255 S111:030 S112=001 S121=000 S130:004 S131:001 S150=000 S151=004 S152=001 S153=001 S154=000 S155=000 S160=010 S161=020 S162=002 S163=003 S164=007 S255:001 Configuration B (tip & kermit dialout) E1 F1 M1 Q0 T V1 W1 X14 Y0 &P0 &T4 Version GA2.00 S00:000 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07:080 S08=002 S09=006 S10=007 S11=070 S12=050 S18=000 S25=005 S26=000 S38:020 S41=000 S45=000 S47=004 S48=000 S49=000 S50:254 S51:252 S52:002 S54:003 S55=000 S56=017 S57=019 S58:000 S59=000 S60=000 S61:001 S62=003 S63=001 S64=000 S65=000 S66:001 S67=000 S68=255 S69=000 S90=000 S91=000 S92=000 S93=008 S94=001 S95=000 S96=001 S100=000 S101=000 S102=000 S104=000 S105=001 S110=255 S111:010 S112=001 S121=000 S130:004 S131:001 S150=000 S151=004 S152=001 S153=001 S154=000 S155=000 S160=010 S161=020 S162=002 S163=003 S164=007 S255:001 Please note that only the registers listed with a colon (:) are changed from the default setting. There is one more register used in both configurations, not listed in the manual OR in the ATN? display. ATS53=003. What is that, you ask. Beats me. I find it odd that S53 is not documented or displayed (even though there is a nice open space to have it printed later, right between S52 and S54). I also thought it odd that the configurations turn OFF modem/host flow control (S58 & S68). Does anyone know what this register is used for? -- Shawn Instenes UUCP:...!nosun!qiclab!redsun!shawni Senior Programmer, Research Dept., Portland (OR) Public Schools Disclaimer: PPS pays me for my work, not my opinions.

S53 is used on the Telebit Plus - and has 6 settings. This register is
labeled Data Carrier Detect and Data Set Ready Interpretation.
The 2500 uses register 130 and 131 in it's place. 130 is Data Set Ready
interpretation, and 131 is Data Carrier Detect interpretation. A register for
each type. 130 has 6 settings and 131 has 4.
2500 with registers 130 and 131 which have
