Supported POS Subsystem Versions

Technote (FAQ)


What version of the IBM POS Subsystem drivers do you support?


Support options for the POS Subsystem (POSS) vary depending on what version of POSS is being used.

POSS for Linux / POSS for Windows

POSS for Linux (POSSLIN) & POSS for Windows (POSSWIN) are supported as stand-alone drivers, but are not available directly for download from the website. If you wish to use POSS you must download the UPOS drivers, which include a copy of POSS.

POSS support and lifecycle information is exactly the same as the UPOS version it was shipped in. For more information refer to R1003632 ("Supported OPOS/JavaPOS Versions")

The following table lists the UPOS version and the POSS version it included with. For completeness sake it lists all versions, even those that are no longer supported.
