Character Generator Commands
The optional character generator supports an on-screen display that is 32 columns (characters) across by 13
rows (lines) down. An imaginary cursor represents the current screen write position. Writing text automatically
increments the cursor to the next character space. The character text is always white.
TM=<label mode>
Example: '>TM=2'
Sets on-screen channel label mode.
0=None
1=Alpha only
2=Numeric only
3=Both alpha and numeric labels
Channel labels are displayed overlaying the video in the top-left corner of the
screen for about 10 seconds after each channel change.
Sets channel mode to display channel number only.
TN=<channel>,<alpha label>
Example: '>TN=8,ABC'
Sets the alpha label for the specified channel. Alpha labels may be up to 8
characters and are displayed on screen when a channel changes, if alpha labels
are enabled by the 'TM' command.
