Parallel to serial with sim reader?

Post by Myrmidon »

Greetings all!

Been reading the forum for ages and decided to join.

I'v decided to make the sim reader as i have all the parts on hand, however, my laptop has no serial socket. I have a parallel tho, so would a parallel to serial converter work for this project?

If not, usb to serial?

Cheers!

:D

That's a 25 to 9 pin serial cable.

Yeah, PC parallel ports are 25 pins, but the gender is opposite, and the pins do completely different things, and at different voltages.

RS-232 is serial. Not parallel.

you could probably bit bang parallel to spi. i think that's pretty much how the parallel port avr programmers work.

Hmm, maybe i'll just fork out for a usb to serial. It would come in handy for other things also.

Thanks.

you cant do parallel to serial as serial depends on very specific timing whereas parallel ports use a latching system
