first part, wait for the acknowledgement (ID CR), and then send the remaining part. If you are using the @S command
with a printer other than the Zebra Cameo or QL3, you may have to change the Protocol parameter in the RF Terminal to
XON/XOFF. This will allow the RF Terminal to deal with the character buffer limitations of your particular printer. If
you are using the O'Neil MicroFlash Printer, you must send a NULL character before the valid data to wake up the print-
er. See your printer manual for details and see Chapter 6 for details on printer protocol.

The @M command is similar to the @S command, except it can be combined with other commands because it is a data entry
command too. This command is for a printer initialization and magstripe input on the Zebra Cameo printer equipped with the
magstripe option. The format of the command is:
where dddatttta might be ! U1 MCR 80 T1 T2+ CR + LF
(Refer to the Cameo manual for the exact string sequence you need to send. The above example sends over an 10 second re-
quest for reading Track 1 and Track 2).
There is no reply to the host except the magstripe data. If the card cannot be read, pressing the ENTER key on the Terminal
will send back ID+CR. This is the breakout method.
This command must be the last in a series of commands. For example, the following would be a typical multi-command
statement:
@C0@1,1,0,Swipe Card@M! U1 MCR 80 T2 (CR)(LF)(EOT)
where:
CR is ASCII 13
LF is ASCII 10
EOT is ASCII 4
The statement causes the RF Terminal to transmit the string "!U1 MCR 80 T2 CR LF" to the Cameo printer. The printer then
wakes up and blinks to indicate the magstripe input is ready to be swiped; when the swipe is complete, the Terminal sends
back the data to the host computer as:
ID+T2:Data on Card+CR (the printer's CR LF stuff is stripped)
If the request is for Track 1 and Track 2, the data sent back is
ID+T1:data on 1+T2:data on 2+CR

Every statement must end with a data entry "prompt" command, whether the statement is a single command by itself or several
commands combined together. Any illegal statement will be ignored as a command but will be displayed on the addressed RF
Terminal display exactly as written. If no Terminal ID was included in the statement, it will try to display the invalid statement
on ID 0. Once the ENTER key is pressed on the Terminal displaying the invalid statement, the terminal sends the Base Station a
"?" character. The Base Station then in turn sends the message n?CR (where n is the Terminal ID and CR is a carriage return)
back to the Host computer.

The "Clear lines" command (@Cx) for the 4 line displays differ slightly from the "Clear lines" command for the current 6 line
displays.

The following table shows the programming differences for 4 lines/6 lines:

In order to maintain compatibility with 4 line display terminals in an existing system, there is a new option in the RF Terminal
Setup for 6 line display terminals. The LCD DISPLAY MODE allows the user to configure a 6 line display terminal as a 4 line
display (centering the data on the display and conforming to the old programming command format, i.e. @C05 clears all lines).
See Installation and Setup for details on how to get into LCD DISPLAY MODE.
