Response Strings
Typical: [Attention] [Unit#] [data ...data] [cr] [lf]
ATSC-mini status response strings contain ASCII characters similar to those used for the same functions in command strings. An ASCII
‘carriage return’ and ‘line feed’ follow each response string. Functions shown as N/A are not applicable or available in the ATSC-mini.
Characters will appear in status strings as lowercase ‘x’.

The ATSC-mini channel status is split into Major Channel and Minor Channel sections. The Minor Channel will always be 000 for analog
channels. The Minor Channel status will display “F00” if the Major channel is a special “one - part” digital channel. Also, as one -part channels
can go higher than 999, the Minor status will indicate how many thousands (up to 63) should be added to the Major number. Example:
Channel 1032 would return 032 for the Major Channel and F01 for the Minor Channel. Two-part channels are limited to 999-999.

Volume 1 emulates legacy 232-series volume level for compatibility with existing applications.
Volume 2 shows actual ATSC-mini level, from 0-100. Audio status will be sent automatically following a volume toggle command from front
panel control, IR remote, or RS-232- command.
