Super L III 39

Your computer may have a 25-pin RS-232C

connector, rather than a 9-pin connector. If so,

use the 9- to 25-pin adapter supplied with Super L

III. This figure shows how this adapter is wired

internally.

Flow Control

Flow control is the process of regulating the traffic or flow of data between two RS-232C

devices. Flow control prevents the transmission and subsequent loss of data if the receiver

is not ready to accept it. Examples of devices that use flow control are: a printer to signal

buffer full; a modem to indicate carrier detect and a time-shared computer that services

multiple users on a time-available basis.
