Missing printf()

What the world needs is a simple program that can be run from the MS-DOS command prompt like this :

writeCom -id com28 -parity none -baud 9600 -stop 1 -data 8

Apparently, even with millions of smart people loose out there, we don't have something as simple as this that people can use. !$@!$#!$#!

The google search that finally got me somewhere was :

dos command line com port writing

Here are some resources :

Available ports?

As it turned out later, all of this stuff is utter crap if you're on WinXP. Why don't people update stuff?
