6 DSR - DCE power er på 4 DTR - DTE power er på

8 CTS - Clear To Send [DCE --> DTE] 7 RTS - Request To Send [DTE --> DCE]

3 TxD - selve Data [DTE --> DCE] 2 RxD - selve Data [DCE --> DTE]

1 DCD - carrier detected [DCE --> DTE] 9 RI - ring indicator [DCE -- DTE] noen ringer på DCE

5 GND

CTS: kommer litt etter RTS

Send by the DCE as a reply on the RTS after a delay in ms, which gives the DCEs enough time to energize their circuits and synchronize on basic modulation patterns.

DCD:

Known as DCD. A signal send from DCE to its DTE to indicate that it has received a basic carrier signal from a (remote) DCE.
