becuase i'm not sure without testing, try this :

SerOut PORTA.3,t2400,[" the first number is : ",b0,13,11]
SerOut PORTA.3,t2400,[" the second number is : ",b1,13,11]

if this works, you know that the w0 item only gives the first (low) byte back.
try then something like that : w0.byte0, wo.byte1 ....
