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.
