- I am working on a project that requires communication via HPIB between
- a 9000/730 running HPUX 8.07 and a 9000/300 running BASIC 5.1. The biggest
- problem is the lack of documentation for HPIB on the 700's. There is quite
- a bit of information for the 600/800 and 300/400 in the HPUX documents
- "Device I/O User's Guide" and "HPUX Reference Volume 3 Section 7", however
- there is no information specific to the 700.
- Consequently I've tried to apply the information for the 600/800 and 300/400
- to the 700 with mixed results. Specific problems/questions include:
-
- 1) Device file minor numbers. I have constructed device files for auto
- addressed files using the minor number format 0x41xx00 where xx is a hex
- number representing the bus address the file is connected to. This appears
- to work fine. The question I have regards a raw bus file, which according to
- 300/400 documentation would have an address of 31 decimal ( 0x1f ). Is this
- true for the 700?
-
- 2) C functions hpib_io and hpib_send_cmnd appear to be missing on the 700.
- By missing I mean prototypes do not appear in the dvio.h file, and they are
- not in the libdvio.a library. In the absence of these two critical functions,
- how can you use a raw bus file to address specific devices on the bus.
-
- 3) On an auto addressed or raw device file, how can you disable a read
- termination pattern. The function io_eol_ctl does not work. I'm trying to
- send binary data, and I can't have a read terminated arbitrarly if two
- consecutive bytes just happen to be CrLf. What I want is HPIB EOI termination
- only.
-
- I've searched the LaserROM/UX library and haven't found answers to
- these questions. Any hints or pointers would be greatly appreciated.
