POWERSCAN ® D8330/M8300172The general format for other asynchronous messages is:[Scanner_Addr] [Scanner_Addr_delimiter] [DC2] MESSAGE [CR]where DC2 is ASCII 0x12 (^R) character.• If you have not enabled the Scanner Address Stamping or the Scanner AddressDelimiter, you must not specify them. In this case all messages will be implicitlyaddressed to the 'binded' Scanner of the cradle directly connected to the serialline.• The Scanner can only receive messages if two-way mode is enabled. (See par.5.9.4, “Transmission Mode”, command is on page 159).• Messages cannot start with '$+' because they would be interpreted as aconfiguration command.• You can send a message to the Scanner only while it is on. This happens whenit has sent a message to the host and the radio timeout has not yet expired. (Seepar. 5.9.1, "Radio Protocol Timeout"; command is on page 130).• If you want to control the Scanner's beeper from the host, you will also probablywant to disable the good transmission beep that is emitted when the code isreceived from the cradle. (See command on page 86).The message field can store plain text and escape sequences.• Escape sequences are interpreted as commands.• Plain text is directly printed on the display. If writing beyond the end of line, thedisplay does not wrap automatically. Extra characters are ignored. Controlcharacters are not interpreted (i.e. LF, FF, etc.).6.1.1 Cursor ControlESC [n A Upn rows, no scrollESC [n B Downn rows, no scrollESC [n C Rightn columnsESC [n D Leftn columnsESC [ G CRESC [r ;c H Move to rowr, columnc(ESC[1;1H is the upper left character position of the display)ESC D Down 1 row, with scrollESC E CR and cursor down 1 row with scrollESC M Up 1 row and scrollNOTES:• Since CR is used as the message terminator, you must use ESC [ G or ESC E toprint a CR.
