Read data (1 word)

Read data (for number of words read)

The text portion of the response’s first frame can contain up to 30 words. If more
than 30 words are read, the data will be returned in multiple frames.

In the second and later frames, the text portion of the response can contain up to
31 words.

If a valid bank number is specified but the PC isn’t equipped with that EM bank,
“0000” will be returned as the read data.

This command can’t be used to change the current bank number.

The INITIALIZE and ABORT commands can be sent instead of the delimiter for
multiple responses for this command. If other commands are sent, they will be
treated the same as delimiters.
