I have a couple of Mitel SX200 systems with hung remote maintenance screens. I can dial into the modem, handshake and connect, but never get to the first menu screen. Just a pretty white screen. I have tried the Esc6 and Esc5 thingy, plus the Ctrl Q,W,E,R,T,Y - B,N,M route and cannot clear the screen. Only way I have ever been successful is to bounce the PBX, and customer does not like this in the middle of the day. Power cycling the modem does not work either. Anybody have any undocumented tricks?
