Does anybody has parallel port multi pic programmer shema?Coz my laptop don't have a serial port.
use an USB to serial adapter.. something like

now you can find those about everywhere.
Or something like TAIT programmer

i can't comment on that one...
Hi,
Development on a PC without a serial port it's almost impossible.
You will need a serial port while debugging or when your program inside
the PIC uses the serial port to communicate with a PC or another device.
The USB to serial adapter is one solution.
Personally I prefer a PC Card (PCMCIA) with real UARTs.

High End PC Cards:
(16550 compatible UARTS and compatibility with 16650, 16750 & 16950).
DUAL SERIAL I/O Cards with removable and non removable DB-9 cables.

OS: Windows 95OB/98SE/Me/2000/XP.
(removable DB-9 cables = you can leave the card inside the slot).

Low cost PC Card
(UART Chipset Oxford CF950, 16C950 compatible).
Low cost dual serial I/O Pc Card

The CB2S650 supports hot-swapping so you’ll be able to connect, use, and swap your serial printers,
digital cameras, PDAs, modems, or any other serial devices without even powering your laptop down.
OS: Windows 9x/ME/NT 4/2000/XP/Server 2003 and up, Linux 2.4x and up

I have the serial converter and a JDM programmer but converter's voltage is not enough.I lower the value of the resistance but this time i am having problem writing the pic.Now i want to ask something may be one of you tryed before.In the shema u can see the JDM programmer circuit.Can we convert this circuit for parallel port?Do u think will it work?
I try all the configrations of the IC-Prog.I can't use Direct I/O when i use a RS232 converter.After than i chose the option Windows API.Still nothing!I invert the data and the others.I tryed 1 by 1 but i cant figure out any thing :(
And now if any body useing USB to RS232 converter and a JDM programmer What re the configrations of the IC-PROG ? Or will i have to use my desktop forever?Or if somebody has parallel port programmer for 16F628 and 16F877 i am only useing these pic's :( I try to make ProPic2 but i couldn't have victory :( I need something simple from parallel port that can program 16F628 and 16F877 thats all.Thanks for the help.
i'm reeeeeeeeeeeeeeeeeally not sure of what i say now, some can confirm. Probably you'll need to use an external power supply or have some kind of level shifter that use the USB power line to raise the voltage...
i remind a previous post somewhere here, i'll try to find it and come back with the link.
One of the best USB and/or Serial multi-pic programmer is here:
http://siscobf.webcindario.com/winpic800.htm
Schematic, .hex, drivers and software as included. And completely FREE.
Support 16Fxxx, 18Fxxxx, 24xxxx and dsPics family.
The soft is in constantly updated.
NO need for a USB converter it is done in the microcontroller.
same for power supply converter from 5vdc to 13.6vdc
Looks good Doctor!
I finnaly found the thread i talked about... if still needed

Modified version of the original PROPIC2.
!!!!! The PCB uses a female DB25. (*FEMALE*)!!!!!!
