Signal ground
Signal ground. The signal voltages are
measured against this line
6
DSR
PGU connected
PGU detection. A connected device is
signalling to the computer that is it ready for
use when there is a logical "1" on this line
7
RTS
Request to send
When this line is set to a logical "1", the
device is ready to send data
8
CTS
