The document specifies additional commands for a CRT-188 card reader. It details commands to read and write the card reader's serial number (S/N). The read command returns the S/N as an ASCII string up to 16 bytes, or a failure code. The write command accepts an ASCII S/N string up to 16 bytes and returns a success or failure code. Both commands use a standard header and response format with status and length fields.
