I am using the 'cu' command to connect to a modem and dial a remote system. An example of one of the commands I might be using is 'cu -s2400 8021234567' where 2400 is the bps, and 8021234567 is the phone number. I have 8 modems connected to the system and I never know which one is going to be free, so I can't specify at any time, when I issue the command the device with an l flag ( -ltty18 ). So my question is, given this setup, is there any way I can find out what device I am connected to after I issue the cu command? Thanks! BRYAN R.

There's also a debug subcommand, somewhere in the ~ escapes -- I forget it offhand, but RTFM and it'll be there somewhere. It shows you the file flags and lots of other good stuff. -- Ed Ravin | I'm sorry, sir, but POSTAL REGULATIONS don't allow cmcl2!panix!eravin | PLASTIC tape over PAPER tape and NYLON cord on an philabs!trintex!elr | 86 inch girth to LITHUANIA... +1 914 993 4737 |

This will, I think, give you the tty of your terminal, not the modem. Although I have not tried it on an RS/6000, I suspect that you can get the handle you want from the lock files in /usr/spool/locks (or the RS/6000 equivalent). -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Dick Gill Gill & Piette, Inc.

OK, I misunderstood. You can use "cu -d <system_name>" and this will show all "debug" output from the connection (possibly messy), or you can do this command from inside of "cu": ~!ps -ef | grep -v grep | grep cu This will show you all occurances of "cu" running, and you can then use the PPID to figure out which one belongs to your process. (Looking at the lock files will work, except that you will not be able to guarantee that a specific lock file goes with your process.) The "cu -d" method would be the easiest, but it will also yield ugly debug text on your screen. +-----------------------------------------------------------------------------+ |The views expressed herein, are the sole responsibility of the typist at hand| +-----------------------------------------------------------------------------+ |UUCP: pensoft!robin | |USNail: 701 Canyon Bend Dr. | | Pflugerville, TX 78660 | | Home: (512)251-6889 Work: (512)343-1111 | +-----------------------------------------------------------------------------+
