GSM (EB066, Generic AT) component
Low level routines for controlling a standard AT GSM / GPRS interface Also available in the form of the EB066 GSM E-block.
Examples
GSM Example
Example should show the following on the display on the panel and on the hardware.
The AT injector component allows us to simulate the response of the GSM module.

Simulation macro reference

Property reference
Expect Echo
This property is of type True or false and can be referenced with the variable name expect_echo.
Sets if we expect an echo of any data we send out to the GSM modem.
Most AT type modems (e.g. GSM modules) will automatically echo back incoming data.
String Array Size
This property is of type Signed integer and can be referenced with the variable name string_size.
Amount of RAM memory to dedicate to receiving responces from the GSM
Message Array Size
This property is of type Signed integer and can be referenced with the variable name message_size.
Amount of RAM memory to dedicate to storing the last SMS message received by the GSM.
Script Count
This property is of type Fixed list of ints and can be referenced with the variable name script_count.
Maximum number of scripts to store in the device's ROM
Script1
This property is of type Multiple lines of text and can be referenced with the variable name script1.
ASCII based AT command data stored in ROM and used when sending script 1
Channel
This property is of type Fixed list of ints and can be referenced with the variable name cal_uart::CHANNEL.
UART Channel selector
Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels.
Hardware channels use the selected peripheral on-board the target microcontroller.
TX
This property is of type Single digital pin and can be referenced with the variable name cal_uart::TX.
Pin to be used for Transmit data
RX
This property is of type Single digital pin and can be referenced with the variable name cal_uart::RX.
Pin to be used for Receive data
Use Flow Control
This property is of type Fixed list of ints and can be referenced with the variable name cal_uart::FLOWEN.
Flow Control (Handshake) enable or disable.
On: Two I/O pins are used to control the flow of data in and out of the device.
Off: Flow control is disabled.
Baud Options
This property is of type Fixed list of ints and can be referenced with the variable name cal_uart::BAUD_LIST.
Baud rate option selector
Baud Rate
This property is of type Signed integer and can be referenced with the variable name cal_uart::BAUD.
No additional information
Label
This property is of type Line of text and can be referenced with the variable name label.
Textual label shown on the component I/O flasher
Scope Traces
This property is of type True or false and can be referenced with the variable name cal_uart::ScopeTraces.
Selects if the scope traces are automatically added to the data recorder window or not.
Simulation - draws an approximation of the UART data onto the scope trace.
ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD.
Console Data
This property is of type True or false and can be referenced with the variable name cal_uart::ConsoleData.
Selects if the console data is automatically generated or not
Console Columns
This property is of type Unsigned integer and can be referenced with the variable name cal_uart::ConsoleColumns.
Number of characters that can be displayed on a single line of the console.
Data Source
This property is of type Fixed list of ints and can be referenced with the variable name cal_uart::DataSource.
Simulation data source used to allow the component to connect to various remote devices
Nothing - Simulation data is ignored
COM port - Routes the communication data to and from a physical or virtual COM port
Injector - Routes the communication data via a data injector component on the Panel.
