A question on printascii

[Shashidhar Hiremath]

HI,
  I want to use printascii to debug my serial driver. How do I enable
it and use the feature.
  Currently I have enabled in menuconfig and done an extern on the
printascii api, this doesn't seem to work, So any hints for debugging
serial drivers ?
