I am posting this for a friend without net.news access. He can receive e-mail, though, so please answer his questions via e-mail to the address below: Reply-to: ZHANG%TAMVXOCN.BITNET@ricevm1.rice.edu He has received one answer to his query from a local user group (included below) that seems to imply that what he is attempting is nearly impossible. I have a hard time believing this, is this terminal so non-standard? or is it the vax? Any help in locating a manual (or photocopies thereof) will surely be appreciated as well. Here goes what he wrote: Ref: Televideo terminial(MDL950) to Vax thru a Modem(Packard Bell2400BPI) ------------------------------------------------------------------------- I am trying to connect TeleVideo terminal to vax thru a modem. With the help of 'Vax users group forum'(Texas A&M only), there are some progress. but i still can not work out. The following is the last mail i sent to the VAXFORUM. ------------------------------------------------------------------------- I connected Televideo to Modem: modem: 1 2 3 4 5 7 6 (8) 20 | | | | | | | | | | | | ----- | ---------- | | | | TeleVideo: 1 2 3 7 I tried both connecting 8 to 6 and 20 and disconnecting 8. The samething happened as this: AT D 8459311 (when i input) CONNECT 2400 (after dial tone) @@y@@@@s@@z@@@$ (after about 30second) NO CARRIER (then the phone line hangs up.) I also tried: modem: 1 2 3 4 5 7 6 (8) 20 | | | | | | | | | | | | ----- | ---------- | | | | | TeleVideo: 1 2 3 7 20 The result was same, but the TR panel light(terminal ready) on the modem was on. The following is the pin assignments of modem, hope this helpfull for Y'all to gave me further suggestions. Pin # Circuit Description Direction ------------------------------------------------------------------- 1 AA protect ground ... 2 BA transmit data TO modem 3 BB receive data FROM modem 4 CA request to send TO modem 5 CB clear to send FROM modem 6 CC data set ready FROM modem 7 AB signal return ... 8 CF carrier detect FROM modem 12 CI select alternate FROM modem 15 DB transmit clock(synch) FROM modem 17 DD receive clock(synch) FROM modem 20 CD data terminal ready TO modem 22 CE ring indicator FROM modem 23 CI select alternate rate FROM modem 24 DA transmit clock(DTE source) TO modem -------------------------------------------------------------------- (DTE: Date Terminal Equipment) Follows Antek's suggestion, I can setup TeleVideo terminal(MDL950) by arrows and 't'key. But there are only 7 fields can be chosen: DUPE or LOCE EDTL or EDTP or INSP or INSL KLOK or none PROT or none GRPH or H.I. or none FDX or BLK or LOC or HDX ... or 1200 or 2400 or ... Is that all? and How to set a terminal like "8bits, no parity", "1 stop bit", "no local echo", and etc.? Does anyone know how to set the FUNCTION switch on the back of a Televideo terminal(MDL950)? ------------------------------------- | on | Swich 2 | 1 2 3 4 5 6 7 8 9 10 | (Function) | off | ------------------------------------- And here goes the only answer he's got so far: ------------------------------------------------------------------------- From: ZAC::VAXFORUM "VAX Users Group Forum" 14-NOV-1989 16:39 To: VAXFORUM-MEMBER Subj: televideo 950 X-Private-Reply-To: ZAC::ROG3217 (14-NOV-1989 16:22:27.66) X-Sequence: 002027 Boy, you guys just don't give up on that Televideo-to-VAX stuff! Here is the number to Televideo Systems, Inc. (408) 745-7760. I spent a lot of time talking to those people trying to get my Televideo 950 to talk to the VAX, but the bottom line was that without special mods it won't work. However, there's the number if you have specific questions about pins and such. If someone does manage to get it to work, please let me know!!! richard griffith ----------------------------------------------------------------------------- So, there you have it, net.land. Does anybody know anything about this? Remember, please contact my friend directly at: Reply-to: ZHANG%TAMVXOCN.BITNET@ricevm1.rice.edu

I just use my normal terminal-cable to connect modem and terminal (to check my x25-software). The pins 1-7 and 20 are connected direct. No problems with different terminals. -- uucp: ...!pyramid!netmbx!altger!snoopy or ...!uunet!altnet!altger!snoopy Snailmail: Mathias Niemz, Preussenallee 23, D-1000 Berlin 19 Phone (Voice !)

Sorry, but mail didn't work - In article <1989Nov23.051359.5263@ntvax.uucp> canoaf@ntvax.uucp (Augustine Cano) writes: >Reply-to: ZHANG%TAMVXOCN.BITNET@ricevm1.rice.edu > >Ref: Televideo terminial(MDL950) to Vax thru a Modem(Packard Bell2400BPI) >------------------------------------------------------------------------- > Our TVI's work just fine. We have 950's and 924's. We use XON-XOFF, and connect 2,3,7 & 20. They are connected to a Develcon Develnet switching system, which connects the terminal to a port on one of the 8650's. When we send them home with people to use with modems, the cable we give them only has 2,3 & 7. We use the following switch settings - S2 - 1234567890 udddduduuu S1 = baud rate for comm port and printer port I don't know if our termcap entry is standard or has been modified.
