Clock Source
The clock source for the synchronous line. The value can be Internal or
External. The default is External.
If you are using a modem, select External.
If a cable directly connects the hardware running the Sun PU2.1 SNA Server
and the SNA Communications Controller, the value you select depends on
whether the Sun PU2.1 SNA Server provides the clocking. If the server
provides the clocking, select Internal. If the server does not provide the
clocking, select External. Note that you must use a special cable to
accommodate the direct connection.
Line Speed
The speed of the connection in bits per second. The value can be 2 400, 4 800,
9 600, 19 200, 56 000, 64 000, 128 000, or 256 000. The default is 9 600 b/s. This
parameter is valid only if the clock source is set to Internal.
Poll Pause Timer
The time to wait before responding to a poll (in 100-millisecond intervals). The
value can range from 0 to 200. The default is 200. A value of 0 indicates no
pause.
Monitor Carrier Detect?
Indicates whether the line should be marked inoperative when the Carrier
Detect (CD) signal is lost. Check the box if the line should be marked. Clear the
box if the line should not be marked. By default, the line is not marked.
Use NRZI Encoding?
Indicates whether NRZI encoding should be used. Check the box if you want
to use NRZI encoding. Clear the box if you do not want to use NRZI encoding.
By default, NRZI encoding is not used.
