Provided that you have working Ex-link connection you can enter following commands (based on T-RBYDEUC firmware)<br />
<br />
==Debug Menu==<br />
Let serial line calm down from huge boot messages and type<br />
debug [ Enter ]<br />
Very complex menu tree follows. You can do lot of things there, especially screw up your TV completely.<br />
<br />
<span style="color:red">BE VERY CAREFUL AND ABSOLUTELY SURE YOU KNOW WHAT YOU ARE DOING</span><br />
<br />
<br />
==Other Debug commands==<br />
I doubt about usefulness of following commands:<br />
<br />
^ [ Enter ]<br />
CPU reset (TV screen is shifted because GPU is not properly initialized) - same as micom 143.<br />
<br />
<br />
keydebug [ Enter ]<br />
keyrec [ Enter ]<br />
keyexit [ Enter ]<br />
Repeats periodically sequence of simulated key presses.<br />
<br />
<br />
==Simulated remote control==<br />
Enter one character code followed by [ Enter ] to simulate a remote control key press.<br />
