I have the Microchip ICD2 debugger which has both USB (preferred) and RS-232
connectors. This works under MPLAB. I am pretty sure that the connection
preferences can be set in MPLAB under the programmer tab.

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.
