3. Go to the PC or terminal connected to the Control (Modem)
Port. Start your communications program. Enter the
Prefix Code followed by the appropriate Port Select Code.
The Control port connects to the selected port and remains
connected until another code sequence is issued.
Notes:
· The Prefix code is sent out the selected port. The
Port Select code is not sent out the selected port
because all ports close briefly upon receipt of the
Prefix code.
· The selected port opens during the Port Select
code's stop bit time. All data following the Port
Select code is sent out the selected port including
the next Prefix code.
Examples:
Assume the Prefix Code is ^V and the Prefix Code Repetition
Value is 4. To connect to Port 14, use the following command:
^V^V^V^VM
Assume the Prefix Code is ^Y and the Prefix Code Repetition
Value is 1. To connect to Port 44, use the following command:
^Yk
4.2. Closing/Opening All Ports
1. To close all ports at once, enter the Prefix code, followed
by a space.
2. To open all ports at once, enter the Prefix code, followed
by ^X (Control X) (CAN)
Example: Assume the Prefix Code is ^V and the Prefix Code
Repetition Value is 2. To open all ports at once, use the
following command:
^V^V^X
