I am trying to set up a dialin line on a PDP-11/23 running TSX-plus from across the country. As you can imagine, it's a bit hard to debug. With the LINDEF set up normally (i.e. without $PHONE or anything special) I can log in fine, but when I logout, or the call terminates, or the connection is broken in any manner, the entire system crashes right down to the @-prompt. When I change the LINDEF to contain a $PHONE switch, this doesn't happen, but it logs me out after approximately ten seconds of connect time. It strikes me that the second method is the right one, if I can figure out how to keep from getting logged out. Is there something special I need in my LINE5.TSX file? Does anybody know how to deal withthis/ ? THanks. GLenn Reid {decwrl,glacier,sun}!adobe!greid -- You have new mail.

Sounds like you have a problem with the carrier-detect signal, either on your modem or on your 11/23. If there's no $PHONE flag, TSX doesn't care about the CD lines; if $PHONE is defined, and CD is not asserted, TSX will think it's lost the carrier and log you out. Check out the hardware ...

I just redid a TSX system to accept a modem, and it worked OK (after getting help from a lot of people via net.decus). I was using a Hayes Smartmodem 1200 connected to a DLV-11J. I tried using the $PHONE flag and this DOES NOT work for this configuration. The reason is that the $PHONE flag makes TSX look for the modem status signals which indicate that it is properly receiving a carrier from the remote modem. If not, it logs you out again. A DLV-11J only has connector pins for data in, data out, and ground, so there is no way to tell it that the modem has answered the phone. The only LSI-11 interface card thgat supports these signals is, I believe, the DLV-11E, which is a single-line serial card (the J is a four-line, non-multiplexed). Anyway, I set the LINDEF up exactly like the other 4 lines, and also changed the macro that defines the total number of lines. One problem that cropped up later is that the other lines had been set for 100-character I/O buffers on the serial lines. This is too small for KERMIT file transfer (to the 11 from a PC), so we will bump iit up to 110. Thre other thing I had to do was tell the Smartmodem not to send result codes or echo commands, else the characters sent (e.g. "RING" bounce back and forth forever). Good luck. I hope that my recent expereince gives you hope. I am sure that others on the net will also be glad to help you. Mike Ciaraldi seismo!rochester!ciaraldi
