*Unused entries in this table were left for completeness even though unused in the
MS246 reader to avoid conflicting definitions between products.
Note not all function ID are present in different hardware versions of the MS246. The last
column above has some codes:
‘-‘ feature not currently supported; exists for compatibility.
‘s’ feature not available in the USB version.
‘u’ feature available only in the USB version.
‘k’ feature not available in the USB version.
‘r’ reset all does not affect this value.
‘n’ not directly settable.
Most function ID settings that relate to the content of formatting of the track output do
not work in secure mode. Exceptions to this are Preamble and Postamble in keyboard
mode only.
It is currently not possible to mix security with OPOS and JPOS support.
