APS-8M Asynchronous Port Switch; User’s Guide
As shown in Figure 7.1, The Port Status Screen lists the following:
• Name: The user-defined name for each port.
• Command Access: Indicates if the corresponding port has been disabled
by the Invalid Access Lockout feature. If this column reads "Locked",
then the defined number of invalid access attempts for this port has been
exceeded, and the port has been locked in order to prevent further access
attempts. To unlock a port, you must either issue the /UL command to
unlock all ports, or wait for the port’s user-defined Lockout Duration
period to elapse.
• Status: The connect status of each port. When the port is connected, this
column will list the number of the other APS port connected to this port.
• Mode: The user-selected Port Mode. This column will read Any (Any-
to-Any), Modem, Passive, or Buffer, depending on the configuration
selected for the port.
• Buffer Count: Lists the amount of data (in bytes) stored in the buffer for
this port.
7.2. The Port Diagnostics Screen (/SD)
The Port Diagnostics Screen provides more detailed information about
each port, including most communication parameters. To display the Port
Diagnostics Screen, access the command mode and type /SD [Enter], the
screen will appear as shown in Figure 7.2.
Like the Port Status Screen, the Port Diagnostics Screen is also available in
both Supervisor Mode and non-Supervisor Mode. Note however, that if the
Port Diagnostics Screen command (/SD) is invoked by a password or port that
does not permit Supervisor Mode, then the resulting screen will only display
status of the ports that are specifically allowed by the password entered
at log in.
