I've seen a lot of projects using pics and PC's, with no interface IC, i think just some resistors. The PIC has a good output current from the serial port and most importantly, the later pics have a configureation bit for the UART to send inverted data. There's a few suggestions here http://www.electro-tech-online.com/microcontrollers/16668-transmit-data-pic-rs232-without-max232.html
I haven't tried it, but if I had nothing to lose I probably would. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
