3.1.108 testSerialExtLoop
Name
testSerialExtLoop—validates the operation of the external serial loopback path. This is a
generic serial external loopback test application that requires an external loopback connector
(configuration of connector is dependent upon the specific hardware design of the board). The
test application verifies the ability of a serial port device to send and receive random ASCII
characters.
Note: This test cannot be executed on internal serial devices (that means, no access for
loopback connector) or serial devices that are needed for essential functions (for example,
MOTLoad console port).
Synopsis
testSerialExtLoop [-d] [-n] [-t] [-v]
Parameters
-d Ps: Device Name (Default = /dev/com2)
-n Pd: Number of Characters (Default = 8192)
-t Pd: RxD Time Out (Default = 30 seconds)
-v 0: Enable Verbose Mode
Example
The following example indicates a typical display when using the testSerialExtLoop
command.
