Ctrl-C in OpenSSH not working

Hello,

I have recently compiled openssh3.5.p1 for QNX4.
(Thank you to Andreas Schneider for providing
the patches!). It seems to work fine, but there
is one little annoying thing and I wonder whether
anyone knows how to get rid of it:
When I connect with openssh the Ctrl-C, Z, etc.
don’t work anymore. I have tried that with PuTTY
and command-line from Linux hosts. The terminal
type is “xterm”. When I try telnet with PuTTY,
it works fine.
Any ideas?

Thank you
