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.

Thanks for confirming that RS232 is an option - do you have any info on
pin
implementation?

There is a Microchip appnote which describes a LPT programmer and
schematic,
does anyone know if it has a RS232 counterpart? - If anyone knows the
document number, I've probably already downlosded it.

The Microchip ICD2 is dirt cheap and you can buy Chinese clones of it on
ebay for about 1/3rd of dirt cheap.

Hard to see how DIYing anything is worth the trouble and an ICD2 will give
you in circuit debug too.

There are a bunch of hits for 'ICD2 schematic' found with Google.
Here's one http://www.nebadje.org/doku.php?id=neblab:icd2clone

Hope this helps you.
Still, as 'nospam' points out, the ICD2 is pretty inexpensive and used ones
should be out there.
