The main routine from 7BitRemoteBoeBot.bs2 was modified to let you change the value
of the
to handle a press/release of the POWER key.
One problem is, what happens if you press/release the POWER key when
(roaming) or 3 (following)? In these two modes, there isn't any way to change the value
of the
beginning of the roaming and following routines that checks for an incoming message
from the remote. This one line of code can be added to the other two roaming routines to
make them respond to a press of the POWER key.
With this one line of code, the first thing the roaming and following routines do is check
to find out if a message from the remote really is coming in. If it is
value of
main routine from 7BitRemoteBoeBot.bs2 will be executed. This routine has a
statement for processing the POWER key and storing a new value in the operation
