is the hardware interface. On an AST LP, this is always RS-232. On an RLP, the
interface is determined by the associated Line Interface Card (LIC) and the cable
attached to the port's I/O box connector. The LP record identifies the LIC, and only
the valid interfaces will be displayed as choices in the Port record. LICs are shown in
parentheses:

disable is performed. (See
specifies the data transmission rate in bits per second, and the clock speed when the
port is a physical DCE. If this port is not configured to generate clock, specify the line
speed that corresponds (as closely as possible) to the configuration of the device con-
nected to the port. Line speed codes are as follows. (Some speeds have two corre-
sponding codes because they are defined in different parts of the software. Either code
can be specified.)

waiting for acknowledgment. If this number is exceeded, no more frames will be
transmitted until an acknowledgment is received.
