Simple PIC programmer
PIC programmer known as COM84. You can find also scheme with 78L05 to supply target microcontroller, but I found powering it from serial port is unreliable (at least with PIC18F2550/4550). Works with i.e. WinPic800 or PICPgm (it is detected as JDM). Programmer may not work with some "modern" or laptop serial ports as it requires about 10 V on TXD pin (to enter high voltage programming mode for PIC18F2550 9.0 - 13.25 V on MCLR pin is necessary).
