External Control Commands

Still (ST)

Command:

Pauses the current file position and freezes the picture.

Format:

ST<CR>

Response:

R<CR>

Explanation:

ST is treated exactly the same as PA except that instead of the video output going black, the current video frame is held on screen. If an ST command is received after a PA the effect will simply be to unmute the video output. Likewise, if a PA is received after an ST, the effect will simply be to mute the video.

Examples:

ST<CR>

Pauses the Firefly and freezes the current frame on each video output.

0@ST<CR>

Pauses the Firefly and freezes the current frame video output.
