RS-232 DTE Loopback Connections

Figure 65. Loopback Connections for RS-232

For Transmit and Receive loopback, connect only those lines.

When Flow Control setting on the

Serial Server

is set for RTS/CTS,

those lines must be looped. Usually DTR and DSR must also be
looped. The Flow Control setting for the program must match the
Server settings. The CD connection is needed by some terminal
programs to simulate Carrier.
