Hardware Effects on OIL Routines
The HP-IB card supported on the Series 800 is the HP 27110B HP-IB
interface; the GPIO card is the HP 27114A Asynchronous FIFO Interface
(AFI).
This section presents some restrictions on using the DIL routines on Series
800 computers. These restrictions are organized under the DIL routine to
which they apply. The routines are presented in alphabetical order. A list of
errno error names can be found in section two of the HP-UX Reference. Errno
numeric values are defined in the file /usr/include/sys/errno.h.
hpib_rqst_srvce
The hpib_rqst_srvce routine only permits bit 6 of the serial poll response
to be set. If hpib_rqst_srvce is called with a response having bit 6 set, the
interface sends <01000000> (64 decimal) in response to serial poll; if bit 6 is
not set in response, the interface sends <10000000> (128 decimal). See "The
Computer as a Non-Active Controller" in Chapter 3.
hpib_io
The atomicity of hpib_io calls is not guaranteed.
These routines are not currently supported on the Series 800.
The AFI driver does not support pattern matching on reads; all io_eol_ctl
calls return -1 and set errno to EINVAL.
