passing ctrl+z key combination

hi,

im looking to pass ctrl+z to a server - console man page says 

1) escape sequence (mine is default 'control-E c'')
2) then type \ooo where ooo is a 3-digit octal code for the keystroke.

according to http://en.wikipedia.org/wiki/Control-Z the octal code for ctrl+z should be 32.

so after typing the escape sequence, typing 

\032

does not seem to send a ctrl+z.  

any ideas ?
