7.3 Modem Control and Status Signals

A serial port has DTR, DSR, RTS, CTS, DCD and RI control lines. RTS
and CTS are locally controlled to prevent local buffer overflow.
However the status of DTR, DRS, DCD and RI can be exchanged with
the remote peer device. If for example, the DTR/DSR lines are to be
exchanged between the two peers to simulate the performance of a
physical cable, then it is possible to do so. Refer to the description for S
Registers 551, 552 and 553 for more details.
