Does anyone have any info on whether MPLAB has RS232 compatible
programmer support?

Having downloaded a number of programmer schematics, I've found that a
couple (Serpic & David Tait) that are very similar to the Velleman K8048
and wondered if this is some sort of industry standard.

If anyone is interested, the examples including Velleman K8048 schematic
are easy to find with google.

The RS232 connector is as follows:

Pin7 (RTS); CLK/RB6/PGC
Pin4 (DTR); DATA/RB7/PGD
Pin8 (CTS); DATA/RB7/PGD
Pin3 (TXD); Pin3 & Pin9 hardwired together
Pin9 (RI); VPP/MCLR(NOT)

Each signal has a transistor buffer/level converter between the RS232
+-12V and PIC logic levels.

TIA.

The ICD2 is RS232 and USB. It has its own micro inside, so Its not a
direct link to MPLAB.
The ICD2 also has its own driver to load to work with MPLAB.
I made the Tait programmer and used Davids software for 16F parts. For the
18F parts I purchased the ICD2 and use the demo compiler.
Programs fast, but debugging is a little slow. (wish they had more break
points)

Cheers



Having spent out already on the K8048 programmer I'm not eager to spend any
more on an ICD2, the K8048 is almost identical to the Serpic2 which
apparently is based on the Tait, so at least I'm not completely at the mercy
of whether Velleman release software updates to support newly released PICs.
