"SWI" - Main Software Version Query
The SWI command is a legacy command which is backward compatible with already existing customer setups (i.e.
product ranges released before Series X). For newer systems and implementations, please use "FWV" command
when possible. Any future revisions, such as CMD additions or changes to the software will increment the software
version. The unit will reply to this command with an ACK attention code. The DATA field will be a ASCII text string
indicating the software version, e.g: "120801V1_M".
