Configuring port parameters

Data Transfer Mode To select the data transfer mode, press the Help (F1) function key and a list is
displayed. Data transfer mode choices are ASCII, Binary and Local Binary (host
port only). Highlight your choice and press Return or the Select Item (F4) function
key.
The data transfer mode selects the type of transfer mode used in back-to-back
connections.
The default setting is ASCII.
Maximum Number of Sessions (for Terminal Ports)
Specify a value between 1 and 5. The maximum number of sessions is the greatest
number of system connections allowed on a terminal at any one time. This value
applies only to terminal ports for which switching is enabled. The maximum
number of sessions on a single DTC is 80.
The default is 3 sessions per port.
Number of Systems Sharing Printer (for Printer Ports)
Specify a value between 1 and 5. This field applies only to printer ports for which
the dedicated printer is disabled. The number of systems sharing printer is the
largest number of systems able to use the printer port at any one time.
The dedicated printer option is enabled or disabled from the Enable Port Options
menu item (see “Enable Dedicated Printer” on page 79 for more details on the
Enable Dedicated Printer option). By default, the dedicated printer option is
disabled.
The default is 3 systems sharing a printer.
Wait Queue Length
(for host ports)
Enter a value between 1 and 5 which corresponds to the largest number of sessions
that can wait for the host port at any one time. This field must be filled.
The default setting is 3.
Note Hewlett-Packard recommends setting this parameter to 1 (single session only) to
avoid the following problem: If a host port that already has an open session receives
another connection request, it queues it. The user sees a message confirming that the
connection has been established, but nothing indicating that the connection is
queued, and may mistakenly believe the port is hung.
