 good suggestion...
 
 been there, tried that [i really _am_ sending to lkml as
 last resort, not first!]

 jiffies equals approx 250? per second?

 baud rate from PIC is determined by GPS - 4800 baud - approx
 600 per second.

 so that'd explain why i only got one character every 3.

 *cold sweat*.  

 i could always use the FIQ, which will be running off the back
 of the Audio DAC/ADC's interrupts, 8khz....

 *shudder*...
