BYO Prop Plug
Is it possible to just wire up a rs232 plug to a header pin for a prop plug for programming?
e.g.
RS232 - > Prop Chip
5 (gnd) -> 9 & 10
3 (txd) -> 31 (rxd)
2 (rxd) - > 30 (txd)
1 (cd) -> 11 (resn)
I searched but was not able to find any topic about building your own programming programmer.

One small problem with my design however. The edge of the board that had the 4 pin connector that would plug into a Protoboard overlapped the power connector on the protoboard. So it was in the way of the power plug or vice versa. After realizing my mistake, the project kinda died.
I was doing it just to prove that it could be done anyway, once I saw that it worked I was satisfied. All of my computers have USB ports and I own 2 PropPlugs, so it was a pointless experiment. Probably wouldn't work on all computers, as there are many different types of RS-232 drivers used over the years.

Would you mind sharing your design? I've got a friend who would like to get started in prop experimenting as cheaply as possible, and I have several MAX233's in my parts box. I'm thinking that a simple cutting of the pref-board (little shaping) should solve the issues with the connectors.

The comments and code above are proof that a million monkeys with a million propeller chips *could* write Shakespeare!
board and programmed with it.. worked ok, i've still got a expresspcb file on it somewheres

might not work with the newer protoboard thou, mine was off a stripboard

If breadboarding this circuit, omit the regulator portion of the circuit, in other words, everything connected to pin 7 of the serial port.
The VCC and GND connections on the IC are not show in this diagram. Be sure to connect pin 15 of the MAX3232 to GND and pin 16 to 3.3V
