The behavior of the tty trigger can be controlled via the Rx and Tx 
file.
If a value is set in Rx or Tx, the LED flashes when data is transmitted 
in
this direction. The same behavior is used for the netdev trigger.
I have therefore used the same pattern for the new tty trigger as well.

I didn't know that the names have to be unique!

I'm a bit at a loss as to what to do now. Should I put a prefix "tty_"
in front of the names so that we have "tty_rx", "tty_tx"?

If we do it this way, however, the general question arises as to whether
we do have to use a prefix everywhere! If new triggers are added, then 
the
names for a config file are already used up and anyone who then wants to 
use
the same name for an other trigger with the same config file because it 
describe
the same function must then work with a prefix!

Best regards

Florian
