Subject: [EE] QBASIC QUESTION


> Does anyone know how to write a QBASIC command to transfer a byte or
multiple sequence of bytes to the parallel port of a PC,  and also to read a
byte or multiple sequence of bytes from the parallel port?  Also, the same
question applies to the serial port.  I would appreciate any information on
this software question.
