5.3.3. Command Availability
The "Commands" field in the Port Configuration menu allows the user to specify which CPM
commands will be available to each port. The user can either select "All" commands or only
"Basic" commands. The "All" option is normally selected for administrator ports, and allows
access to all CPM commands. The "Basic" option is normally selected for user ports, and
allows limited access to CPM commands. Section 8.3 summarizes "All" and "Basic"
commands.
In the default state, Port 1 is the only port with access to "All" CPM commands. When ports
are configured, at least one CPM port should be granted access to "All" CPM commands.
5.3.4. Port Configuration Commands
The following section describes the procedure for using the Port Configuration Menu to select
options for each port.
Note that parameters and options selected via the Port Configuration Menu will stay in effect
until the CPM is initialized using the /I command or the CLEAR and SET buttons. When the
unit is initialized, parameters will revert to the defaults specified by the Setup Switch
configuration.
After parameters have been selected, the configuration can be saved to an ASCII file on your
PC. Later, if the CPM configuration is altered or deleted, the file with the saved parameters
can be sent to the CPM to automatically reconfigure the unit without the need to manually re-
define each parameter. Section 7 provides a description of the procedure for saving
configuration parameters to an ASCII file.
To select port parameters, proceed as follows:
1. Access the CPM Command Mode.
2. Type /P, followed by the number of the port to be configured, and press [Enter]. For
example, to configure Port 2, type /P 02 [Enter]. The Port Configuration menu will
appear as shown in Figure 5.1.
The Port Configuration menu offers the following options:
1. Port Name: Allows the user to assign a name to this port. For example,
"MODEM". Up to eight characters.
2. Baud Rate: Defines the baud rate for this port. The Baud rate can be set to any
standard rate from 300 to 38.4K bps.
3. Bits/Parity: Defines the data bits and parity for this port.
4. Stop Bits: Defines the stop bits for this port.
5. Handshake: Defines the handshake format for this port. The handshake can be set
to XON/XOFF, DTR (hardware), Both, or None.
