Hello.  My company is using Telxon PTC-710s running Dos 3.21 with a proprietary clipper ORDER entry program.  

Anyway, one of our users wants the volume increased, so that when she scans an item, she can HEAR the little click beep sound.  

I know its possible to change the speaker volume on this thing... we were able to do it in a previous version of the software... I was just wondering if there was a DOS command that could do this POSSIBLY, or if it was purely a clipper function.  Unfortunately, the person who wrote this software left a few years ago, so I'm left trying to support these things not knowing anything  

Thanks for your help.

FredThe PC Speaker offers no support of volume control in DOS and minimal (PCSpeaker WAV Player) in Windows. Get small 3 or 4 cell audio amplifiers that you can get away with running on the system 5v bus (or 12v bus if they're 8 cell amps) and connect them to the PC speaker output and add a volume control. You can EITHER get these as little add-on amps for Walkman/Discman portable players, or as IC projects from Radio Shark or similar ELECTRONICS stores.
