Module. This parameter represents the line module number in the source unit.
Port. Enter the port number where the source stations reside.
After these fields have been filled, press F10. This re-displays the port using the
copied values.
Baud Rate
This is the rate, in bits per second, at which the port communicates. The selections
are 300, 1200, 2400, 4800, 7200, 9600, 12000, 14400, 16800, 19200, 24000,
28800, 38400, and Auto.
Bits per Character
The number of valid data bits in each byte is represented in this field. The
selections are 7 and 8.
Parity
Parity selections can be Odd, Even, or None. Setting the parity of a byte of data is
accomplished by marking the most significant bit (MSB) either on or off so that
the total number of on bits is either an odd or even number. Odd and even parity
are used when the bits per character are set to 7. When 8 bits per character are
used, the parity is set to None. Odd parity should be selected for sync lines, while
Even should be selected for async and TDI. The selections are O (odd) and E
(even).
Message Buffer
The message buffer represents the number of internally transferred bytes the port
accumulates before beginning to transmit the data to the attached device. If the
current port speed is less than or equal to the speed of the port transferring the
data, this parameter can be set to 100. If the current port speed is faster than that
of the transferring port, this parameter must be greater than the largest possible
message size. This acts as a fast-output option. When set to 100, the message is
sent to the terminal device while it is still being received from the host. When set
to a value greater than the actual message size, the entire message is received from
the host before being sent to the terminal device. If any terminal on this port is
linked to a port using a transport protocol such as X.25 or Frame Relay, set this
parameter to 4096. The selections are 10 to 4096.
Interface
This field is not used in the 9111 (but is used in other TXPORT products).
Algorithm
The algorithm field determines the flavor of Poll/Select used. The selections are S
(specific), C (contention), and G (group).
Termination
This field is not used in the 9111 (but is used in other TXPORT products).
