What is the address for the serial output port for a personal computer. One of the computers is a toshiba lap top from 1994 the other a packard bell from about 1996. I've tried to find it using q-basic, but I'ts tough to find becuase the contents of some of the possible addresses are canging.
Would there be any difficulties in putting lets say 10 8051's togetther to make a parellel computer. Would the 8051's be able to send data to each other at 3 MHz. Any difficulties writing a parelles program?
