Description
daqIOReadBit allows you to read a specified bit on the selected device and port. The read operation will return the current state of the
selected bit in the bitValue parameter. The selected bit (specified by the bitNum parameter) corresponds to the IO channel on the port
which is to be read. The bitValue will be TRUE indicating a high state or FALSE indicating a low state.

Description
daqIOWrite allows you to write to the specified port on the selected device. The write operation will write the settings indicated in the
value parameter to the selected port. The value written will depend on the width of the selected port. Normally, for byte-wide ports, only
the low-order byte of the value parameter will be written. The IO channels for the port correspond to each bit within the value written. If the
channel is to be driven to a high state, then the corresponding bit should be set. Likewise, if the channel is to be driven to a low state, then
the corresponding bit should not be set.
