Description

These tests verify API and operation of the USART modem lines handling functions.

The data exchange tests verify the following driver functions (USART Driver function documentation):

• SetModemControl

  int32_t                SetModemControl (ARM_USART_MODEM_CONTROL control);

• GetModemStatus

  ARM_USART_MODEM_STATUS GetModemStatus  (void);

Note

These tests are not executed if any of the following settings are selected:

• Test Mode Loopback
• Tests Default Mode Synchronous Master/Slave or Single-wire
