to the Uniscope terminal port. When set to (Y) yes, the proper conversion will take
place. For now, this parameter should always be set to N (no). The selections are Y
(yes) and N (no).
Maximum Select before Poll
This value represents the consecutive number of selects that are sent to a device
before normal polling resumes. This prevents a locking condition where a terminal
constantly NAKs a select because it has a message to send. The selections are 1 to
255.
Active If DSR/DCD

active. The physical DTE/DCE setting of the port also effects how these leads are
interpreted as shown in Table 9-2. No polling occurs on the port until the selected

or a select. The selections are 0 to 655350, 3000.
Maximum Messages Queued

accumulated for a station before a NAK is transmitted to the sending device. The
selections are 1 to 32, 4.
Activity Timer
The Activity Timer is the time, in minutes, that no data can be present on the port
before the unit disconnects the line. This is used primarily in dial-up applications.
Line disconnection is done by lowering the DTR signal for 500 milliseconds and
raising it again. Entering 0 disables this feature. The selections are 0 to 255.
