It's a simple one-line change in /etc/ssh/sshd_config:

    Port 21499

instead of "Port 22" and then restart sshd.

On the Linux/Cygwin client side it's a command-line parameter or an
entry in ~/.ssh/config, as in

    host thor
    hostname ip.add.re.ss
    port 21499
    user fred
    identityfile ~/.ssh/fred.dsa

Other devices usually have a way to store the desired port.
