Interfacing With Parallel Port in PERL
Hiya, I am currently working on a project to output informatgion to an 20x4 LCD on a parallel port, but i cannot seem to find any modules or documentation, on how to interface the port, i am newish to perl, and all i have used it for before is CGI stuff, but i have decided to use perl for this project, as i find it such an easy language to work with Any help, or pointers will be greatly appreciated Thanx oO_RoB_Oo

If your operating system can access the parallel port as a device file, use it as a file. If not, expect to have fun writing extensions in C which you can link into your perl code. Quote: > oO_RoB_Oo

Interfacing With Parallel Port in PERL
Does Linux access the parallel port as a device file? On Fri, 14 Apr 2000 23:39:54 +0200, Thorbjoern Ravn Andersen Quote:

I would say so yes :
/dev/par0 /dev/par1 /dev/par2 /dev/parport0 /dev/parport1 /dev/parport2 However you would want to ask in a Linux group about that. /J\ -- Don't eat me. I have a wife and kids. Eat them. -- fortune oscar homer

If I understand the question, the only folks that reference a parallel port any more are those using a browser on a PC therefore limiting the OS's to W95/W98/WNT/W2K or Linux. Being able to select the Parallel Port on a Windoze PC would be nice, but I would also like to spool to the default or a selected Windoze PC user-defined printer. Leave it to auditors to come up with this sort of requirement. So, is there a module or plug-in available such that when a user clicks on a file link, it spools directly to a user selected printer without first being displayed. The auditors theory is that if you can display if first, you can save it, alter it, then print it. Unfortunately he is correct. So, now I need to come up with a way to achieve this. One other problem is that the files reside on a central server (Sun SunOS) and the users that need this functionality are on opposite sides of the country us Wxx PC's. SunOS 5.6 Netscape (iPlanet) Server V4.1 Browsers: IE 4, 5 and Netscape 4.0-4.7 Any ideas, Michael Austin Oracle DBA Consultant
