E - Echo Control
For machine driven applications, echoing the command input is not always helpful. This can
be disabled by sending a E0 command and re-enabled by sending a E1 command.
V - Version Request
This command causes the UFI to respond with its current software version, preceded by a v
Q - Query
This command returns the current input and output channel states.
A - Anti Modem Detection
In order that a UFI will not be confused by PC software automatically scanning for dial up
modems, any command starting with an A (e.g. ‘AT’) will return error.
Gtext - Generate Key
For special applications, the UFI can generate a 32 bit key based on the text supplied in this
command. There must be at least 8 characters of text supplied, and the unit will only generate
a certain number of different keys in any time period. The key is returned as 8 hex characters,
e.g. ghhhhhhhh.
Ntext - Save/Read Non-Volatile Text
For special applications, the UFI can store a string of up to 32 characters in its non-volatile
memory. If a string is supplied, it is stored, if not, the last stored string is returned.
