IRIX64 Keymapping

jhwilliams · 05-17-2007, 12:58 PM

Hi, we have a 16 proc IRIX here - I've never used this OS before. My backspace and delete keys are not working when I remote login -

The backspace goes to a fresh commanline, and the delete key puts in a ~. Is this is standard behaviour on IRIX, and is there anyway to change it so it acts your standard GNU/Linux system, where you can actually delete things if you make a mistake?

Thanks!
Jameson

I think the problem is probably with the terminal emulator your are using.

These programs tends to remap backspace (Control-H, 0x08) and delete (0x7f) to something else.

Run also "stty -a" on the IRIX box to see what character is used to erase.

Code:

octopus:/home/jameson% stty -a
speed 38400 baud; line = 1; 56 rows; 153 columns
intr = DEL; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = ^@; old-swtch = ^Z; susp = ^Z
lnext = ^V; werase = ^W; rprnt = ^R; flush = ^O; stop = ^S; start = ^Q; dsusp = ^Y

Ctrl-H of course! Why not. I am rlogin from a tcsh shell on GNU/Linux. Any ideas for remapping ? Thanks

It could have been delete, which is the default on System-V UNIX.

This doesn't answer the question about the terminal emulator used.
To make sure rlogin and tcsh aren't responsible of the issue, you can try login with telnet and running a bourne shell (sh/ksh/bash).

That would depend on the terminal emulator settings.

When connected to the IRIX box, does a plain Control-H erase the last character and Control-W the last word ?

Code:

% telnet octopus

-- yea, bash through telnet is the same deal. :-(

Can you answer my previous questions:

What is your terminal emulator: gnome-terminal ? xterm ? konsole ?

When connected to the IRIX box, does a Control-H erase the last character and Control-W the last word ?

jhwilliams · 05-18-2007, 04:23 PM

Ah yes! Sorry. I am using gnome-terminal. And yes, Control-H erases the last character, Control-W erases the last word. Thanks

Reset the backspace and delete keys to send what God intended, not these broken "compatibility values":

Code:

Edit -> Current Profile -> Compatibility ->
  Backspace key generates "Control-H"
  Delete key generates "ASCII DEL"

jhwilliams · 05-21-2007, 09:26 AM

Thanks! Well, the Backspace key now works, but the delete key is skipping to new lines. If I use "escape-sequence" I get a tilde. If I use ascii-del, I get the new command line skip. This is also happening on an AIX 43 machine, and a solaris64 machine. The functionality one would expect of the delete key appears not to be bound to any sequence now listed from

Code:

stty -a

on the IRIX machine (octopus).

Code:

octopus:/home/jameson% stty -a
speed 38400 baud; line = 1; 40 rows; 185 columns
intr = DEL; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = ^@; old-swtch = ^Z; susp = ^Z
lnext = ^V; werase = ^W; rprnt = ^R; flush = ^O; stop = ^S; start = ^Q; dsusp = ^Y

opost -olcuc onlcr -ocrnl -onocr -onlret -ofill -ofdel

And on the solaris:

Code:

hermes:/home/jameson% stty -a
speed 38400 baud;
rows = 40; columns = 185; ypixels = 0; xpixels = 0;
csdata ?

And on the AIX:

Code:

delaware:/home/jameson% stty -a

eucw 1:1:0:0, scrw 1:1:0:0:

eol2 = ^@; start = ^Q; stop = ^S; susp = ^Z; dsusp = ^Y; reprint = ^R

opost -olcuc onlcr -ocrnl -onocr -onlret -ofill -ofdel

Thank you very much for your help so far! Achievement of the backspace key is a major advancement in the quality of my daily routine :-)

jlliagre · 05-22-2007, 03:51 PM

The delete key is mapped to interrupt (usually Control-C on most platforms) on the IRIX machine, this is what you call "Command Line Skip".

On the Solaris box, delete is erasing the last character and backspace does nothing in particular.
