Set by user to enable loop-back mode. In loop-back mode, the SOUT is forced high. In addition, the modem
signals are directly connected to the status inputs (RTS to CTS, DTR to DSR, OUT1 to RI, and OUT2 to DCD).
Set by user to force the RTS output to 0.
Cleared by user to force the RTS output to 1.
Set by user to force the DTR output to 0.
Cleared by user to force the DTR output to 1.
Set by user to enable generation of an interrupt if any of COMxSTA1[3:0] are set.
Cleared by user.
Set by user to enable generation of an interrupt if any of COMxSTA0[3:1] are set.
Cleared by user.
Set by user to enable interrupt when buffer is empty during a transmission.
