* ProbeRS232_InitTarget()
*
* Description : Initialize the UART for uC/Probe communication.
*
* Argument(s) : baud_rate Intended baud rate of the RS-232.
*
* Return(s) : none.
*
* Note(s ) : (1) The following constants control the GPIO remap for the USART control lines:
*
* PROBE_RS232_UART_1_REMAP
* PROBE_RS232_UART_2_REMAP
* PROBE_RS232_UART_3_REMAP_PARTIAL
* PROBE_RS232_UART_3_REMAP_FULL
*
* Though the #error directives in "Local Configuration Errors" will require that
* all are defined, the value of those bearing on the USART not used will have no
* effect.
*
* (2) PROBE_RS232_UART_3_REMAP_PARTIAL has precedence over PROBE_RS232_UART_3_REMAP_FULL,
* if both are defined to DEF_TRUE.
