If successful, the specified card returns the following:
(describeDevice card_id num_buffers buf1 ... bufN)
where each of the available buffers generates a description bufi containing the buffer ID and the corresponding buffer length in bytes, as follows:
(buffer_id length)
length is in bytes.
This command provides information about the buffers associated with the specified card, specifically the number of buffers and the size in bytes of each buffer. This command can be used by a client application to obtain information about the card. This command is not used in a configuration file.
