If I have a PC program that accesses a serial port. I have a PC with no serial port, but do have a USB port. Can I make the USB port into a serial port with one of those USB/serial port adaptors. The question is can I make the program send and recieve data to the USB port when no serial port is present. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
