Umm... not really.  A serial port is *typically* a 9 pin connector 
although was originally a 25 pin connector.  However there are *a lot* 
of cases where serial ports are not the familiar 9 pin connector.  There 
are many server applications where an RJ-45 connector is used (see Digi 
PortServer and Etherlite for example).

In this particular case the serial port could look like a phone jack.  
The one on the back of my RCA Directv receiver is.  Be careful though it 
actually uses a handset modular connector, a phone line cord won't fit.
