Hello, I have used the turbo power (now opensource) component for serial port I/O: http://sourceforge.net/projects/tpapro/
Its very reliable, works well, and has examples with sourcecode; I would advise against using USB directly (it needs the programming of a driver specific to the hardware whereas the serial port is more generic): the use of a USB/serialport converter as advised in other mails is a good alternative; Kevin _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
