ISerial::RequestToSendState

Description

Manually asserts or deasserts the Request To Send (RTS) output signal.  When the ASRL_FLOW_CNTRL attribute is set to ASRL_FLOW_RTS_CTS, this attribute is ignored when changed, but can be read to determine whether the background flow control is asserting or unasserting the signal.
