That does make the assumption that pins and code are free and that the CPU 
isn't already occupied with other time critical functions. ;).

I don't know about the original poster but I place some value on my 
time.  For a strictly debug it may well be cheaper to simple hang some HW 
off a header to SPI or I2C even if the chips are more expensive than a 16550.
