231 characters in length. A message cannot though, contain an @S

command in combination with any other command. A message

also should not contain more than 1 request for data entry (third

character in command is 1). For example:

@1,1,1,ITEM@2,1,1,QTY

has two data entry “prompt” commands combined. If this message

were sent to the RF Terminal, the first data entry prompt

(@1,1,1,ITEM) would be executed, but any and all commands after

the first data entry prompt in that statement would be ignored

without warning – there will be no display or indication of an illegal

command.

The @S command (for serial output) statement cannot be

combined with any other command - even clear (@Cx) commands.

After a @S command is successfully completed, the Base Station

sends back to the host the RF Terminal ID followed by a CR

(ASCII 13). There is a 231 character limit on data for this

command. If you send a command of more than 231 characters,

you will get an Illegal Command returned, (ID ? CR). If you need

to send 300 characters of data, send the 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

printer. 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:

@Mdddatttta(EOT)

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 request 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.
