Command Packet 0x8E-2B - Request Fix and Channel Tracking Info, Type 2<br />
This packet requests Packet 0x8F-2B or marks it for automatic output. If only the first<br />
byte (packet sub-code 0x2B) is sent, an 0x8F-2B report containing the last available<br />
data will be sent immediately. If two bytes are sent, the packet is marked/unmarked<br />
for auto report according to the value of the second byte as shown in below.<br />
To retain the auto-report setting for this packet, first set the setting accordingly and<br />
then save to non-volatile memory by issuing the packet 0x8E-26.<br />
