Configuration / Operation 143
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, 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
Setting the parity of a byte of data 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 parameters is
set to 7. When 8 bits per character are used, the parity is set to None. Use Odd
parity on sync lines, Even on async. 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).
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).
Trailing Pad Characters
Pad characters are dummy characters sent at the end of a synchronous transmission.
Use two PAD characters for sync lines, and 0 on async lines. The selections are 0
to 2.
