Included Documentation

PDF user manual available as separate download

Note

  • Even though the serial driver is a QNX native device driver, it requires the MDIS kernel server for the M-Module carrier (e.g. D203). Therefore, the 'MDIS4/2004 system package for QNX' is also required.
  • This driver needs revision 1.3 or higher of the MDIS4 system package. You can find the revision number of the current MDIS4 package in the history file of the package.
