-// tty_printf()
-// This function is a simplified version of the mutek_printf() function.
-// The terminal index must be defined in the calling task context.
-// It doesn't use the IRQ_PUT interrupt, and the associated kernel buffer.
-// Only a limited number of formats are supported:
-//   - %d : signed decimal
-//   - %u : unsigned decimal
-//   - %x : hexadecimal
-//   - %c : char
-//   - %s : string
-// - Returns 0 if success, > 0 if error.
