6. Operation
6.1. Port Connection and Disconnection
This section describes the procedure for using ASCII commands to make and break connections
between CPM ports.
The CPM allows communication between devices without the requirement that both devices
use the same communication parameters. This allows the user to connect devices that use
dissimilar baud rates, parity, handshake, and etc.. The CPM converts data rates and other
communications parameters, eliminating the need to select common parameters for all
connected devices.
6.1.1. Using ASCII Commands to Connect Ports
Two different types of connections can be made between CPM ports; Resident Connections and
Third Party Connections.
In a Resident Connect, your resident port issues a /C command to connect to a second port.
For example, if Port 4 issues the /C command to connect to Port 5, this is a Resident Connect.
In a Third Party Connect, your resident port issues a /C command to create a connection
between two other ports. For example, if Port 1 is your resident port, and Port 1 issues a
command to connect Port 2 to Port 3, this is a Third Party Connect.
Note:
Port Names are case sensitive. When invoking the /C command, make certain to
note the case of each letter of the Port Name.
Ports that have been granted Basic (User) command capability, can only use the /C
command to perform a Resident Connect. Ports with Basic command capability
cannot initiate a Third Party Connect.
To Connect CPM ports, proceed as follows:
1. Access the CPM Command Mode.
2. Invoke the /C command to connect the desired ports.
a) Resident Connect: To connect your resident port to another port, type /C nn and
press [Enter]. Where nn is the number or name of the port you want to connect.
Examples:
To connect your resident port to Port 8, type /C 08 [Enter].
To connect your resident port to a port named "MODEM", type /C MODEM
[Enter].
