A single alphanumeric character is used to indicate the device type. The devices in Polycom's
EchoFree family have the following device types.

T
Device type '*' can be used to send a command to all device types simultaneously.
4.2. Device ID
Two numeric characters are used to indicate the device ID. The Vortex can be configured for device
IDs from '00' to '07'. Note that even though the device ID is less than 10, the leading '0' must be
included. Device ID '**' can be used to send a command to all device IDs simultaneously. Some
examples of using wildcard characters are given below.
'S**' broadcasts to all EF2211 devices that are linked together.
'*07' broadcasts to all devices with device ID 07 (this format is not commonly used).
'***' broadcasts to all devices that are linked together.
4.3. Command Name
The command name can be from 1 to 7 characters long. Command names will be specific to device
types. In other words, the EF2280 has its own command set, which is different from the EF2241's,
which is different from the EF1210's, etc. There are some commands, such as 'PING', that are
common among all the various command sets.
4.4. Command Data
The command data is a series of 0-64 characters containing payload data for the command.
Obviously, the command data will be specific to the command type. note that the maximum number
of payload characters for the EF200 and EF1210 is 32, but the Vortex devices support up to 64
characters in the payload. This increase was necessary to accommodate the matrix gain and
macro/preset commands.
4.5. Command Terminator
The command terminator is a single character indicating the end of a command. ASCII 13 (^M) was
