I think you can Telnet SOE with 800. Here is my note for 2400:
Telnet SOE to AP
telnet <controller-ip> 2300 (must allow soe in config telnet soe)
soe> connect 1/0 (AP is in controller 1 port 0)
reboot ap and hit enter within 3 second to get to rom monitor
purge, save, boot will set AP to factory default, or you can set static IP address:
apboot> setenv ipaddr <ip add of ap>
apboot> setenv netmask
apboot> setenv gatewayip
apboot> setenv master <ip of master>
apboot> setenv serverip (usually ip of master)
apboot> printenv (or print)
save
boot
