I have a horrible time getting this to work. I have a hayes modem connected to a tt port. Kermit can see tha modem fine, let me dial out, let me do my work, etc. I'd like to use set host/dte. Uh-uh. That let's me get to the modem, but I never see anything come back.. The modem is sending it to the system, cause if i drop out of set host and jump into kermit, I can see that my data was getting there and I start getting output from that point. If I switch back to set host, no data. Needless to say, this makes it impossible to use dynamic decnet... Any ideas on why this happens? Do I need a magic cable? (I've tried 2-3-7, and all 50) Magic terminal settings? (various combinations tried, including modem and nomodem and parity and bit settings.) Help! I especially need this now, cause that system is isolated from the rest of campus due to that fact that its ethernet cable caught fire. (Don't ask, it's hard to explain, just trust me.) Getting that connection back would pick up 5 systems that are stuck right now. -Ron

Sounds like you might have that port set to /notypeahead. SET HOST/DTE won't work with /notypeahead set. The best thing I've found to do in this case is to leave the permanent characteristic set to /notypeahead, then allocate the device when you want to use it, and then set it to /typeahead (without using /perm). Then, when you deallocate the device, it will fall back to /notypeahead.

on a case like this, a breakout box is essential..... BUT, from memory, a lot of hayes modems DO NOT put out all of the modem control signals that a vax wants/desires and ,again from memory, I thought that the simplest way to do this is via brute force (after all this is an emergency) wire cable as follows: modem vax 1 -------------------- 1 (use 1 AND 7, some modems use 7 -------------------- 7 others 7) 2 -------------------- 2 3 -------------------- 3 4 - - 4 (some modems/ third party muxes | | require rts/cts - able mux- 5 - _ 5 master for instance) 6 - - 6 | | 8 - - 8 | | 22 - - 22 (tie these together and then | | 20 - - 20 tie them to each own's 20...) a little less brute force (if the modem DOES generate the right signals is to send (6,8,22) to the OTHER sides 20...... -ed cetron ps. 1 Prot gnd 2 tx 3 rx 4 rts 5 cts 6 dsr 7 sig gnd 8 cd (rlsd) 20 dtr 22 ri

What is the truth? Response: We use the $set host /dte command extensively here and with great success and usefullness. It is not true that this command can only be used with DEC modems. The $set host/dte command serves as a mechanism to logically connect you with the specified line and route the input from your terminal or device down that line. Therefore you can use this command to connect to any line with any number of possible devices connected to it. As one of our devices we use Hayes 2400 smart modems and it works fine. We use this command extensively when Kermitting files. However the command $set host/dte/dial=(NUMBER:number) TTXX: uses an image called Sys$library:dte_df03.exe to automatically call the specified number using the DEC DF03 modem protocol. Alas, the sources for the image are supplied by DEC in the file Sys$examples:dte_df03.mar to be used as a template for users to modify the code to talk whatever protocol your modem speaks. We have successfully converted the code to talk to our Hayes modems and built the image Sys$library:dte_hayes.exe and then use the command: $set host/dte/dial=(NUMBER:number,MODEM=hayes) TTXX:. A possible suggestion to your line allocation question might be to put an Access Control List (ACL) on each of the lines and then Grant these ID's in Authorize to the desired users. As a side benefit, this could provide a kind of load leveling mechanism. Mike Pung (Pung%ornl-ncc@ornl-msr.arpa) Martin Marietta Energy Systems Oak Ridge, Tn ------
