padOn

Checks for the existence of a pad and initializes communications. Normally this command searches all valid COM-ports for
the existence of all supported Transaction Team pad types. This command must be executed before using the library; the
only exceptions to this are the commands padSetPort, padSetPortAddr, padSetPortIrq, and padSetType, which modify
the behavior of padOn and must be called prior to calling padOn. This function is similar to padConnect except that it will
never attempt to connect to a pad if a connection is was already established. The padOn command can only be issued once
if it succeeds until a padOff command is issued. If you wish to reconnect to a pad, use the padConnect command instead.
Syntax
BOOL padOn(
void
)
Returns
Returns TRUE if successful, FALSE otherwise.

padPassThroughOff

Turns off pass through mode. While in pass through mode, all pads in pass through mode connected together in a chain
monitor the data passing through them. If any of the pads see the padPassThroughOff command and the correct code
passed along with it, then that pad will disable pass through mode. If the code is incorrect for a pad seeing the command,
then that pad will not process it. It simply passes the padPassThroughOff command through to its pass through port as if
it was normal binary data. Whatever device is connected to its pass through port then will receive the padPassThroughOff
command. If there is another pad in pass through mode that is connected to its pass through port, and if the code is correct
for that pad, then that pad will disable its pass through mode.
