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 is
used when the Bits per Character parameter is set to 7. When the 8 Bits per
Character parameter is selected, set the parity to None. Use Odd parity for sync
lines, and Even parity on async line. 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, 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 determines the interface type of the port. The hardware DIP switches for the
port must be set to match the software setting (9000 card only). The selections are
A (async) and V (V35).
Timeouts to Mark Offline
This field determines the consecutive number of times a station can timeout before
the unit marks it offline. The selections are 1 to 255, 3.
Termination
The termination parameter relates to the 9000 series product only. It sets the port
for DCE (data communication equipment) or DTE (data terminal equipment).
