Here is an example of a terminal emulator setup session. In
normal font are the various parameter types. In bold type are
the values that should be used for best results. Your terminal
program's setup screen may differ from this one:

XON/XOFF software flow control:
CTS/RTS hardware flow control:
DSR/DTR hardware flow control:
Clocking: Network (default)
Options:
Network: This is the most commonly used setting when connect
ing to a carrier's network. In this mode, the unit recovers the
clock from the received signal and uses it to transmit data. In
this way the unit remains synchronized to a master clock.
Incampus applications, one of the units must be set to Internal
clock, and the other end is set to Network clock. At all times,
there must be only one clock source. Otherwise, clock slips
and framing errors and bit errors may occur.
Internal: This is commonly used in campus applications, where
the unit is not connected to the public telephone network
directly. In this mode, the unit uses the on-board oscillator as
the transmit clock source.
Line Build Out (dB): 0 – 133 feet, 0 dB (default)
Options:
This controls the transmitter signal strength and pulse shape. For
most applications, the default setting will suffice. When connecting to a
carrier connection, the carrier will determine what LBO is necessary.
0dB provides the highest signal strength and therefore the longest dis-
