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. Block transfer is implemented since OZ version 4.5.
Other information of this call can be found in the The Serial Interface section.

If you set the default to $FFFF then when the default is used (by setting a timeout value of $FFFF in get and put byte routines) then the system will wait forever. A soft reset sets the default timeout to 10 minutes. This timeout is completely independent of the system timeout, which is set by the Panel.
