I am on windows XP and when I run IRB ruby version 1.8.7-p249 I get a  
STTY error

G:\>irb  
stty: Unknown mode: g  
stty: Unknown mode: icrnl  
irb(main):001:0\>

Where can I fix the IRB sty call?

Thanks

If you can’t explain it simply, you don’t understand it well enough.

Which stty.exe is it calling? It’s probably calling into a wrong one,  
like cygwin or something…

It is calling the wks version…, is there a way to edit what irb is  
calling?

I think it calls out to “stty.exe” and “if it’s there, uses it, if not  
ignores it” (I’m just guessing here, but I think so).

Anyway work arounds might be to remove the wks version from your path,  
possibly to set the TERM variable to something different…

That was the answer. Windows in this case works if you set the TERM to  
nothing:

C:\set TERM=
