Full details of this call's reason codes are found below. This interface is used by OZ internally, and don't work on application level. For Application level serial port I/O, use GN_Opf to get serial port handle and use OS_Gb / OS_Pb to transmit data. Applications might use OS_Si to reset serial port buffers, and interact with the Panel. ...
A slot, in this context, is the set of bits required to transmit on character. This will include 8 data bits plus start and stop bits.
