We cover serial data transfer, interface pinouts, port speeds, serial interface varieties (DB9 DB25), null modem wires and very much more.Its pinouts are usually a lot simpler when compared to the parallel interface, but the quickness is also a lot slower.
Db25 Serial Cable Pinout Serial Data TransferThats pretty slow when youre utilized to a network link, but let me display you how serial data is moved so you can furthermore know why its a lot slower.
