Let me repeat the question couse I firstly send it in scripting which I think was bad idea...
I need something simple from mikrotik, sending 0x00 or 0xff (off,on) to printer port 0x378 or whatewer values to whatever ports, so I can do a script of pinging something, and when it is dead for a while, I turn off/on some device wich is connected to relay connected to lpt port.
P.S. Does someone find this feature interesting?
