2.3.1.12 921 kBaud COM Select

This command switches the serial COM speed to 921 Kbaud. The actual COM speed is 968571
baud due to the reader’s crystal frequency. The host application should match this actual speed in
order to minimize transmission errors. The reader response to this command is to issue the reply
0xC0 0x03, then switch to 921 Kbaud. The host, having received this reply, switches its COM
speed to 921 Kbaud.

After a reset command, the reader re-opens communications at the stored baud rate. The 921
Kbaud setting is not stored, so the reader cannot open at this speed. The host either remembers
the original COM speed or auto-detects the reader settings.
