hi,
I found a shortage in such a component:
MIDPTerminal: J2ME MIDP Canvas Terminal Component (Simple Console for MIDP)
check http://cellbasic.sourceforge.net/midpterminal/
* Category: Software > J2ME > MIDP > Canvas
* This canvas serves as a terminal, CLI, console, command line, low-level textual input
* Provides low level UI input/output along with graphics.
* Allows interactive command line interface (CLI) for MIDP applications.

regards
Mustafa
