'COM84 and NT4.'

I am looking for a Win NT program to drive the COM84 serial PIC blower
before I start a project to write one does any one know if such a thing
already exists (if so I don't want to re-invent the wheel).

I use PIP2 in DOS - but sick of all the reboots to switch OS's.

Thanks,

PaulF.

I guess from the lack of replies that none of you guys out there are
using NT4 and COM84 type programmers. Looks like I will be writing a
blower after all (downer). Does anyone know where I could find PD source
code (DOS, WIN311 - C, ASM, Pascal are all fine) to kick start me, once
done I will make the blower PD and put on to a WEB page somewhere
(just in case someone moves to NT4 with COM84 hardware).

Paul,

There has been quite a bit of discussion on the list about driving simple
parallel/serial port programmers from windows.  The conclusion seemed to be
that although it can be done, but that there will always be an uncertainty
in the timing of the programming pulses.  Jim is (or was) giving away the
hex code to turn a parallel port style (e.g.Tait) programmer into a serialy
driven one using a 16F84, this would seem to be a far more reliable way to
go, although obviously not as convenient as COM84 from the point of view of
supplys etc.

Regards

That's why my software only supports the 16C84/16F8x chips :-).

With 16 bit Windows (3.x/Win95/Win98) it's not too bad getting timing
down to 1mS, but with 32 bit Win NT it seems MUCH! harder.

I'm presently considering using Timer3 to generate the timing delay, I
currently have it working from DOS, next I will try it under Windows 95.
Is their anyone on the list who knows is you could use this under NT?.
