^C doesnt work on ssh session

[Sudarshan Soma]

Hi ,
when i connect to sshd ,  the session doesnt allow me to issue ^C ^Z, it
doesnt work.  Please let me know if there are any settings to control it.
telnet works fine.

my settings, version:

OpenSSH_6.6p1, OpenSSL 1.0.1h 5 Jun 2014

stty -a
speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt =
^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

another query i had was on hiding arguments passed to ssh. I have  a
requirement to spawn some ssh command like (ssh ip -o password=221 ip )
which has password in arguments. can we hide this in listing from ps ,
/proc outputs. Please suggest.
