Port. The number of the source port to be copied from is entered here.
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, and 38400.
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 data byte is
done 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 parameter is set to 7. When 8 bits per character is
selected, the parity is set to none. The selections are O (odd), E (even), and N
(none).
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, then 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 (X.25 or Frame Relay), set this parameter to 4096.
The selections are 10 to 4096.
Interface
This determines the interface type of the port. The only valid entry is S for Sync.
Any other entry is ignored. The selections are S (sync/RS-232) and V (V.35). This
is not used for the 9111.
Maximum Messages Queued
The value in this field indicates the total number of messages that can be
accumulated for a station before flow control is invoked. The selections are 1 to
32, 4.
