In line turn-around mode, the KeyAT-5 sends a
colon prompt after the data has been processed,
signaling that it is ready for another command.
Below shows the ASCII characters ‘DIR<ENTER>’
being sent via the KeyAT-5.
Example:
KeyAT, V5.0x1, [C]L3 Systems, Inc.

Commands
Commands are instructions to the KeyAT-5 to do
something other than just pass data through to the
computer. All commands begin with a ~ (tilde, hex
7E) character followed by a command character,
and in some cases additional data.
~@
Disable Commands – All commands are
disabled until 10 consecutive tildes
(~~~~~~~~~~) or reset/power cycle.
~~~~~~~~~~ Reset/Enable Commands – If
commands are disabled, sending 10
consecutive tilde (~) characters will enable
commands. If commands are enabled, this
will reset the KeyAT-5 (& run power-up string
if loaded).
