Serial parameters It is not necessary to configure the Interface for the serial transmission parameters (baud rate, data format and parity). The transmission speed can be selected as desired between 300 and 19,200 baud. The corresponding hardware handshake lines are jumpered on the RS232 side, ...
Types of Serial Cables To makeserial communicationpossible between DTE and DCE, two types of RS232 cables exist. They are Null modem and Straight-cable. Innull modem cable, the TX (Transmitter) pin of the male connector is linked up with the RX (Receiver) pin of the female and the RX ...
