The command to transmit the break signal is break.
"set break (time)"
Specify break time to time.
The break time can be set in bits or microseconds. When setting in bit units, you only need to enter the value, but when setting in microseconds, you must put "us" after the value. The available setting value is from 10 bits to 60 seconds.
※ Note: The actual break time may be longer than the specified time when system is busy.
