Description

The CALL RTR_START_TX command causes a command server to call the

rtr_start_tx( )

routine using values supplied on the command line.

The numeric status returned from the call is then converted to its textual
representation and displayed.

The

rtr_start_tx( )

routine itself is described in Application Programmer’s

Reference Manual.

The prototype of

rtr_start_tx( )

is:

rtr_status_t

rtr_start_tx (
