Gary,

Here is a partial reply, other stuff may deserve a thread of it's own.

From this heading in the pdf that you referenced.
CONFIGURE NMEA MESSAGE – Configure NMEA message int
erval (0x8)

These values look to me to be the default.

  #0 ~255, 0:disable
  #GGA 01
  #GSA 01
  #GSV 01
  #GLL 00
  #RMC 01 -- 255 appears to be what sets NMEA response to top of second...
  #VTG 00
  #ZDA 00
  #Attributes 0x00, 0x01 -- sram, or sram/flash

The "-- 255 appears.." comment is from my notes, sending the string that 
follows will indeed change the output to send very close to the top of 
second.  I see no way to check/query these values, only set them.  The 
command does ACK properly.  I would note that you need to save this to 
flash for the device to use it right away, it does appear to do a hot 
restart after the ACK.

Yes, that looks to be what I used when I had it hooked up to a Windows 
box.  I never captured/saw exactly what command was sent though.  At 
this point I'm choosing to not go back to the Windows only route...

I'll try that command later and see what results I get.
