Seems that, to your controller, the most significant bit is expected to be aways set, the 4th bit sets the lights and the 5th the bell. So you can store the start state (or we could call it reset state) "128" in a variable, toggle the state of each bit with XOR bitwise against a mask and interpolate with a command to receiver "<f 1108 ...

To start only (not toggling) you could check the state with AND against the interest mask, if state is off the AND result is zero (or false):


my $state = 128; # start state, binary: 1000 0000
my $lightmask = 16; # 0001 0000
my $bellmask  =  8; # 0000 1000

sub togglelight {
   $state = $state ^ $lightmask;
   $port->write("<f 1108 $state");
   $port->lookclear();
}

sub bellon {
   if (not ($state & $bellmask)) {
      $state = $state ^ $bellmask;
      $port->write("<f 1108 $state");
      $port->lookclear();
   }
}

sub belloff {
   if ($state & $bellmask) {
      $state = $state ^ $bellmask;
      $port->write("<f 1108 $state");
      $port->lookclear();
   }
}
