  • Page 6: At Command Syntax

    AT COMMAND SYNTAX Commands There are three forms of AT Commands: Action, Question and Help. For cases where there is no stored value for the command it cannot be questioned. Commands start with AT and finish with a carriage return (<CR>) or a line feed (<LF>) character. Action Action commands can take one of three forms: AT<command><CR>...

  • Page 8: Command Support

    Command Support Radio models with P25 capability (ie. CM60 models) support all commands listed in this document. Analog only radios (CM40, CM50) do not support commands related to P25 functionality or data calls. Commands related to P25, P25 trunking or data calls may also be disabled depending on the radio’s feature licensing and channel selection.

  • Page 26: Eeprom User Storage Area

    EEPROM USER STORAGE AREA An area of the EEPROM is set aside for user (3rd party integrator) storage. This information is accessed by AT commands as raw bytes. There is no formatting or structure imposed by the radio on this area. As per the following figure, the EEPROM address range from 0 up to, including, 255 is available for user storage.

  • Page 27: Slip Extended Control Byte

    SLIP Extended Control Byte A further extension to the SLIP protocol has been implemented (including escaping XON/XOFF char- acters as described in 13.2) using an additional control byte in the beginning of the SLIP frame. This control byte allows additional information to be passed ‘out of band’ between the DTE and DCE as a bitfield.
