Setting Up Remote Console Management

Verifying Serial Port Connections 3-15

This option generates 15 lines of 50 characters each of a

printable sequence of ASCII characters to be sent to the

destination port. You can enter values from 0-65535. The

default is 23. If you enter 0, the test port runs

continuously until you enter CTRL-C. An end of test

message is displayed.

L You must use the “width” parameter in the same

command if you want to use the “lines” parameter.

4. Test the port async port with loopback:

Example InReach:0 >>test port async loopback

This option generates 23 lines of 80 characters each of a

printable sequence of ASCII characters to be sent to the

destination port. The rules of this option are as follows:

• A "loopback" connector requires that the "transmit"

wire be tied to the "receive" wire.

• If a parity, framing, or overrun error occurs, it is

recorded as an error as part of the end of the test

message.

• If the "loopback" connector is not being used or it is

wired incorrectly, the command fails because there is

no data to read in from the destination port.

• The "loopback" option is not valid if the source and

destination port are the same.

• The appropriate messages will be displayed in the

above cases.

• If a "loopback" connector is connected, but you do not

specify the "loopback" keyword, the port records the

characters transmitted out and received in, but no

character received is checked for integrity.

• The "loopback" option is also valid with the "width"

parameter and the "width and lines" parameters.
