sutest Command-Line Syntax

dev=device_name

Identifies the serial port(s) to test. There is no default value. You must specify a device name such as su0.

porta=port_name

The name of the first device of a serial device pair. The default is a.

T=test_type

Specifies the type of test to run: 

• a= runs the test on port a.

• b= runs the test on port b.

• a_b= runs the test on ports a and b sequentially.

• a_b_concurrent= runs the test on port a and port b concurrently.

• a_to_b= runs the test from port a to port b.

L=loopback_type

The type of loopback connector attached to ports: 

• Internal_a_to_a__b_to_b

• Null_modem_a_to_b

• Plug_a_to_a__b_to_b

D=data_pattern

Selects the data pattern to transfer. The user can select: 

• Random

• Sequential

• Alphanumeric

• 0x00-0xFF

AB=baud_rate

Asynchronous baud rate (default = 9600). The valid values are between 110 - 460800.

Note: Some platforms can only support asynchronous baud rates up to 38400 or 76800. For baud rates greater then 153600 the serial line drivers must be set for RS-423 mode and not RS-232 mode.  

BS=write_size

Asynchronous mode write size; from 1 to 10000 bytes. 

F=flow_control

Asynchronous mode flow control 

• Hardware (RTS/CTS)

• Software (xon/xoff)

• None
