Features and benefits
The PCI dual-port programmable serial interface (PSI) card consists of 2-port serial interface hardware that features a flexible physical connectivity interface (RS-232C/V24, X.21/V11, RS-449, V.35,
or RS-530 standards). Cable types are automatically recognized.
It supports the X.25/LAP-B protocol allowing HP 9000-to-HP 9000 communication, as well as HP 9000 to other systems (HP or non-HP) over packet data networks or leased lines. This is achieved through
the use of HP X.25/9000 Software (P/N J2793B).
