I'm runnin Ultrix 1.2A on a MicroVAX II, and I have the 16-user version.
There is an Emulex controller pretending to be 16 lines of DHV, which seems
to show up when the system is booted (dh0 and dh1). I am having lots of
trouble using the second group of 8 lines.
When the system was set up, /dev contained tty00 - tty07 plus ttyh0 - ttyh7.
It appeared that I wanted ttyh* entries, so I created 8 more with the same
major device number and minor numbers from 8 to 15. This may have been
the mistake.
When I try to output to these new entries, such as cat >/dev/ttyh8, the
system immediately crashes, complaining that it overflowed the timeout
table.
What is the correct way to set this up?

It is specified by `ncallout'. In 4.3BSD, this is by default 16+NPROC; NPROC is 20 + 8 * MAXUSERS; MAXUSERS is the `maxusers' line in the configuration file /sys/conf/FOOVAX. `maxusers' has nothing to do with the maximum number of users, and really should be called something boring like `global_system_size_parameter'. As a quick hack, do this: % su Password: <whatever> # shutdown ... # then wait; once down: # adb -w /vmunix ncallout?D _ncallout: _ncallout: 164 # current size is 164 entries ncallout?W 0t328 # so just double it # fastboot # and try that. If that fixes it, that was it. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) Domain: chris@mimsy.umd.edu Path: seismo!mimsy!chris

This may have been > the mistake. I believe there should not be a problem with this device assuming the hardware settings are correct on the board. A few months ago I helped a customer install Ultrix-32 1.2 on a uVAX with the same controller. Suggestions: 1. Make sure that the board is set up to look like a DHV (!!!!) and not a DHU (see the Emulex manual -- you may need to change a few switches... we did.) 2. remove the terminal nodes in /dev -- assuming you only have the "dhv", "rm /dev/tty?*" should do it. 3. remake the terminal nodes -- "cd /dev; MAKEDEV dhu0 dhu1" (make sure you use the MAKEDEV script!) At this point try it again... Fred

These were set up so that tty00 through tty07 were mapped to the DHV11, ttyh0 through ttyh7 to ports 0 to 7 on the CP34, and ttyi0 to ttyi7 to the CP34 ports 8 through 15. Here's how we did it... The DIP switches on the CS04 board must be properly set. The table belows show these settings. CS04 DIP Switch Settings ------------------------ 1 2 3 4 5 6 7 8 SW1 open(0) open open open open open open open SW2 off(0) off off off off off off off SW3 off off on(1) off off on on off SW4 off on off off on off off off These lines in the kernel config file describe the port arrangement. The DHV-11 is "dhu0", and the CS04 is both "dhu1" and "dhu2": device dhu0 at uba0 csr 0160440 flags 0xff vector dhurint dhuxint device dhu1 at uba0 csr 0160460 flags 0xff vector dhurint dhuxint device dhu2 at uba0 csr 0160500 flags 0xff vector dhurint dhuxint The tty files are a bit more complicated. Since our port configuration is slightly unusual, MAKEDEV won't produce the port mappings that we want. We have to create the files by hand; a pain, but the only way to do it right. The "ls -l tty[0hi]" command should produce output looking something like: rw--w--w- root 33,0 Feb 20 10:22 1987 tty00 rw--w--w- root 33,1 Feb 20 10:22 1987 tty01 rw--w--w- root 33,2 Feb 20 10:22 1987 tty02 rw--w--w- root 33,3 Feb 20 10:22 1987 tty03 rw--w--w- root 33,4 Feb 20 10:22 1987 tty04 rw--w--w- root 33,5 Feb 20 10:22 1987 tty05 rw--w--w- root 33,6 Feb 20 10:22 1987 tty06 rw--w--w- root 33,7 Feb 20 10:22 1987 tty07 rw--w--w- root 33,16 Feb 20 10:22 1987 ttyh0 rw--w--w- root 33,17 Feb 20 10:22 1987 ttyh1 rw--w--w- root 33,18 Feb 20 10:22 1987 ttyh2 rw--w--w- root 33,19 Feb 20 10:22 1987 ttyh3 rw--w--w- root 33,20 Feb 20 10:22 1987 ttyh4 rw--w--w- root 33,21 Feb 20 10:22 1987 ttyh5 rw--w--w- root 33,22 Feb 20 10:22 1987 ttyh6 rw--w--w- root 33,23 Feb 20 10:22 1987 ttyh7 rw--w--w- root 33,32 Feb 20 10:22 1987 ttyi0 rw--w--w- root 33,33 Feb 20 10:22 1987 ttyi1 rw--w--w- root 33,34 Feb 20 10:22 1987 ttyi2 rw--w--w- root 33,35 Feb 20 10:22 1987 ttyi3 rw--w--w- root 33,36 Feb 20 10:22 1987 ttyi4 rw--w--w- root 33,37 Feb 20 10:22 1987 ttyi5 rw--w--w- root 33,38 Feb 20 10:23 1987 ttyi6 rw--w--w- root 33,39 Feb 20 10:23 1987 ttyi7 Note that all the major device numbers are 33. This is because all the ports are on (or look like they're on) DHV11's, the major device number of which is 33. The minor device numbers are what distinguish the ports from one another, and they must be created exactly as shown. The minor numbers have a gap in 8 out of every 16 numbers. This is because the DHU-11 driver is being used to support the DHV-11 devices, and the DHU-11 has 16 ports per controller, compared with the DHV-11's 8. Since the Emulex CS04 is emulating two DHV-11's in this case, the gap must be used. To create the files, use the mknod command when logged in as root. To create tty00, for example, you'd type (while in /dev) "mknod tty00 c 33 0". To create ttyi1, you'd enter "mknod ttyi1 c 33 33". Easy? Good. Now do it 24 times, one for each port. -- Andrew Siegel, N2CN NBC Computer Imaging, New York, NY philabs!nbc1!abs (212)664-5776
