Type in the command: ATI9I9 <CR>
An AT is not required in front of the second I9 command

. You only need one attention code for each
command line. To make this command more readable, you can add spaces between the two commands:
Type in the command: AT I9 I9 <CR>
The modem will execute the command as if the spaces are not there.
Port Selection Modifier
Unlike conventional modems the RFI-9256 has two serial ports. Each can be configured
independently. So to allow access and configuration of alternative ports a modifier may be appended to the
end of the command string.
This modifier is a colon followed by a port number from 0-1. For example ‘:00’ would be port 00 also
called the Main port, ‘:01’ would be the Auxiliary port.
Typing in the command: ATS80:01 <CR>, would connect the port to the auxiliary port of
the remote unit addressed 80 (Rx = 80).
The Escape Sequence
When there is no communications link established to a remote modem, and you issue commands, all
dialogue is occurring between your computer and the local modem. This situation is known as Local
Command State.
When you connect to a remote modem, dialogue is occurring between your computer and the remote
modem (or what is connected to the remote modem). This is known as On-line State. Once a modem
enters on-line state, it assumes all the data you send it is to be sent on to the remote modem, so it ignores
any AT commands you give it.
To force the modem to return to local command state, enter an escape sequence. An escape sequence
consists of a one second delay, three characters (default is ‘+’) typed rapidly and another one-second delay.
For example if you dial a remote modem:
Type: ATDT 2000 <CR>
If the remote modem connects then the local modem will enter the ‘on-line’ state and your terminal will
display the message CONNECT.
Now try to view the modem’s firmware identity code:

There are some commands that cannot be linked as multiple commands. These commands have to appear on their own and are
outlined in the tables on page 70.
