5.1.8 Opening Tab
Where and when a serial port is open for communication is decided here. The following screen is for
SER1, but the rest of the serial ports have basically the same parameters to set. In fact, SER3 configured as
a 9-wire port has exactly the same parameters as SER1. The rest differ in the choices for “Incoming con-
nections” and “Active open.”
Figure 5.10 Opening Tab for SER1
Local TCP port
This is the local TCP port number for incoming connections from the network. When
acting as a server, this is where the serial port listens. Set to zero to make this entry
unused. Port numbers less than 1024 are reserved; they are used for internal function-
ality and standard services such as web server and telnet.
