beeper
The beeper generates a beep tone. It is typically used to announce the start and/or completion
of a test or operation. Available commands:
beeper.enable
beeper.beep()
bit functions
The bit functions are used to perform bitwise logic operations on two given numbers, and bit
operations on one given number. Logic and bit operations truncate the fractional part of given
numbers to make them integers. Available commands:
bit.bitand()
bit.bitor()
bit.bitxor()
bit.clear()
bit.get()
bit.getfield()
bit.set()
bit.setfield()
bit.test()
bit.toggle()
channel functions and attributes
Use the functions and attributes in this group to control and query switching channels. Unless
specifically noted, ch_list specifies the channels or backplane relays in a comma-delimited
format on which the function is to be performed. Available commands:
channel.clearforbidden()
channel.close()
channel.connectrule
