PB/DOS on hand held devices

[Charles Kincaid]

Has anyone run a PB app on a hand held bar code scanner I.E. Telxon, PSC, Intermec?

If so, how to you get to the laser scanner and how do you communicate to the host through th 2.4Ghz radio link?

You mean, "Using a hand-held device" rather than "running on a hand-help device?"

If so, scanners and the like are generally peripheral I-O devices, and are accessed on the using computer as either a keyboard device, serial or parallel port device or through an I-O port. A radio tranmission may appear to programmer as a series of "keystrokes" or "commmunications port characters" or as an interrupt, handled transparently by the software.

I think Charles is talking about programmable bar code scanners; they have some kind of DOS in ROM, included MS-DOS 6.x, and they are often programmed in C but in theory they might be programmed through any DOS compiler.
Personally i saw several such scanners, right from Intermec, running C programs, but unfortunately i don' t have any info regarding PB/DOS, however i would find it very interesting.

Yes, that is exactly what I am talking about. Intermec, Telxon, Symbol, and others make DOS based devices. They have C libraries that you link (statically) into your executable.

I am wondering if anyone has made it happen in PB-DOS?
