This section lists the confirmation status codes that the scanner may return
when processing a BT. Some of them are duplicates of those listed in
chapter 7, Scanner Management.
Please note that the xlat_con routine (described in chapter 7, ”Scanner
Management”) can also be used to translate BT confirmation status codes.
Table 8.A

SC_OK 00 (hex) completed successfully
SC_BAD_PARAM 11 (hex) invalid parameters to a valid command
SC_BAD_REQ 10 (hex) invalid command (can occur only if the first argument to
