FINS Commands Section 5-3
Message (response)
Each message is returned in numerical order, from smaller to larger, accord-
ing to the message number. Each message consists of 32 ASCII characters
(32 bytes). The total number of bytes of the messages is calculated as fol-
lows:
The number of messages read × 32 bytes
If a message consists of less than 32 bytes, the remainder will be filled with
spaces (20 hex). If no message has been registered for a message number
that has been requested, 32 bytes of spaces (20 hex) will be returned.
End code (response)
Refer to 5-1-3 End Codes for information on end codes.

20) commands share the same command code (0920). They are distin-
guished by bits 14 and 15 of the two-byte parameter following the command
code. To read MSG(195) messages, bits 14 and 15 must be OFF (0).
