The current ppbus code layers so : +--------------+---------+-----+------+ | ppa3/vp0/Zip | new_lpt | ppi | ?? | +--------------+---------+-----+------+ | ppbus primitives | +--------------------+----------------+ | ppc (ISA chipsets) | ? | +--------------------+----------------+ ppc ISA parallel port access code (works, need more chipset support) ppbus Bus code (works) ppa3 Parallel Zip driver (works) new_lpt Traditional printer driver (works, polled mode only) ppi User-space parallel port access (under development) Notably, there is no 'lp' replacement yet. The new code will coexist (but not share ports) with the old 'lpt' driver, so I think it's time to give it some wider exposure, particularly if this shakes any more bugs (or developers) out. ftp://smith.net.au/ppa/ppbus-970730.tgz -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
