Select 2), from the Network Configuration Menu configures Handshaking, Baud Rate, Word Size,
Stop Bits, and Parity through either the serial or Ethernet ports using the menus. RTS and DTR Line
Drivers can only be configured through the phone line via a modem. The default settings are
9600bps, 8 data bits, no parity, one stop bit, RTS and DTR High.
IMPORTANT: Communications with the terminal computer connected to the port will be lost
until the serial port configuration of the terminal computer matches the unit’s serial port.

For a simple communication between modems three connected lines are needed: TX, Rx, and Ground.
For the data to be transmitted, both sides have to be clocking the data at the same baud rate. While this
method is sufficient for most applications, it is limited in being able to respond to problems such as the
receiver getting overloaded. This is where serial handshaking can help.
