Patch applied to git head.  Thanks!

If you are interested in the serial behavior of a u-blox then you
will be interested in two new commands added yeasterday to ubxtool.

For u-blox 5 to 9:

# ubxtool -p MON-IO
ubxtool: poll MON-IO
sent:
UBX-MON-IO:
 Poll request

UBX-MON-IO:
  Port: 0 (DDC)
   rxBytes 0 txBytes 0 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0
  Port: 1 (UART1)
   rxBytes 0 txBytes 104171017 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0
  Port: 2 (UART2)
   rxBytes 0 txBytes 0 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0
  Port: 3 (USB)
   rxBytes 182740 txBytes 11767546 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0
  Port: 4 (SPI)
   rxBytes 0 txBytes 0 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0
  Port: 5 (Reserved)
   rxBytes 0 txBytes 0 parityErrs 0 framingErrs 0
   overrunErrs 0 breakCond 0 reserved 0


New for u-blox 9:

# ubxtool -p MON-COMMS
ubxtool: poll MON-COMMS
sent:
UBX-MON-COMMS:
 Poll request

UBX-MON-COMMS:
version 0 nPorts 4 txErrors 0x0 reserved1 0

The txPeakUsage on USB is interesting.  That shows that at
one point since restart the USB port was 39% full and some
messages were "skipped".

Not exactly sure what that means, but it is data that is now
easy to see.

Yes, I note the two Port 1.  That is at odds with the u-blox 9
doc.
