I suggest the "Perl Cookbook" by Christiansen and Torkington. It is good reading to go through just to see new and more advanced techniques are done and has a lot of real-world examples that you can cut and paste into your own scripts. ><And now, the Challenge>.. > >There are many Technical Measurement-Instruments with a >"RS-232" Interface... so, why not obtaining data via "serial cable" ? ... >Or can you give me some hints, where to start, when listening to a "Serial >Cable" ? >where are the "hurdles" which are awaiting me ? You are adventurous! Serial port programming is probably one of the most challenging of all the "network-type" programming. I've attempted just enough "for fun" to know I didn't have the time to try and work out all the issues. A lot will depend upon the device to which you are connecting. It will depend upon how forgiving it is on which RS-232 signal is present when. It will also depend upon the serial port out which you are speaking. What I was attempting was using an old desktop PC, loaded Linux on it, and wanted to use the COM 1 serial port to talk to a console port of a device. I ran into many issues of locking up the console, locking up the Linux box, etc, etc. Here is one link to a Linux Serial How-to: http://www.linuxdoc.org/HOWTO/Serial-HOWTO.html and then here's another http://www.linuxdoc.org/HOWTO/Serial-Programming-HOWTO.html You've got some great ideas, Reini. Keep plugging on the perl skills and you'll be writing those really fun scripts in no time! Patrick --- Patrick Bartkus, CCNP Certified Sr. Network Support Analyst Fleet Mortgage (soon to be Wash.
