Anyone with a replacement Printf?

I'll be publishing it soon. I have fputc() fgetc(), etc. done.

The problem is that the existing IFI printf library doesn't exactly lend itself to creating an fprintf() routine, and a "printf()" on top of that (i.e. default output to one or the other ports).

Maybe I just need a primer on how printf(...) works... But I thought I would ask and see if someone has a version that would be more amenable to the streams approach to output.

The original goal was to have the debug menu on one port and still have access to another port for serial peripherals (say, a GPS unit?) But just having it buffered and polling makes a HUGE difference in performance and ability to debug with printf statements.

You can just call the one routine that prints decimals without changing any of your own printfs.

PS- why do you have to have at least 2 characters?
