Linux: DU/RD units etc<BR></FONT><BR></DIV>
<DIV></DIV>'lo all...<BR><BR>I've been fiddling with the standard VAX
emulation under Linux and it's all working Ok... but I can't find the answer
to this question in the FAQ nor in the docs.<BR><BR>I understand that to get
data in/out of the VAX/VMS environment, I need to create an ISO9660 .iso file
which I can then mount as a CD-ROM -type device inside the VAX
emulation.<BR><BR>However, it seems there is a limitation of only 4 DU-style
devices. For example, when I set-up a 'standard' installation as
described in Phil Wherry's <I>Running VAX/VMS Under Linux Using SIMH</I>
guide, he uses a vax.ini file that sets-up 3x virtual RA92 disks and 1x
virtual RDD40 CD-ROM. If I modify the vax.ini file or manually enter
commands in the simulator to manipulate another RDD40 device (so that I can
get files into the emulation), I get into strife,
viz:<BR><BR><X-TAB> </X-TAB>simh>
show
rq4<BR><X-TAB> </X-TAB>Unit
disabled<BR><X-TAB> </X-TAB>simh>
set rq4
enable<BR><X-TAB> </X-TAB>Command
not
allowed<BR><X-TAB> </X-TAB>simh>
show
device<BR><X-TAB> </X-TAB>...<BR><X-TAB> </X-TAB>RQ,
address=(...), no vector, 4
units<BR><X-TAB> </X-TAB>...<BR><BR>Now,
seeing the vax.ini file talks about rq0 through rq3, this 'adds-up' that we
only have 4 units available... but how do I get to another unit? Is
there a compile-time option? Something that needs to be included in the
vax.ini file? Is the vax.ini file only used the first time the emulator
is started, hence I need to re-start the emulator with new virtual disks,
etc.?<BR><BR>Also, a trivial sort of question... Under Linux, both xterm
and aterm -types of virtual terminals don't send the correct key for
"backspace" (they send CTRL-H instead of DEL). I assume there's someting
in an .xtermrc file or similar that will fix that up? -- I'm none too flash
when it comes to Linux :)<BR><BR>Thanks for any forthcoming
info.<BR><BR><BR>John<BR><BR><X-SIGSEP>
