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 DOS
POSSDOS is no longer supported as a stand-alone driver; support expired at the end of 2011 per our announcement in R10004604
(System units may be advertised as supporting DOS, but that does not necessarily mean that they support POSS for DOS)
POSS for OS/2
POSSOS2 is no longer supported. The OS/2 operating system is no longer supported.
POSS for Linux / POSS for Windows
POSSLIN & 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.
