I am looking for an interface between 2 computers, the first for generate sequences of characters (simulates a keyboard) those are input to the second by keyboard connector and acting like a real keyboard. So, i need the ideea for the interface and the software. Thnx you in advance !!!

pheeeeewww...... i'm glad this question is for 'newbies'

Do your KBcontroller research,

for software, look at "expect", it is a TCL
extension, and is perfect for simulating an
"operator".

If you know C/TCL you can modify expect to
do just about what you want.

for an example; my previous employer had
a custom database running on an ultrix box.
the database had a primitive query interface.
We wrote some custom "expect" code to supply,
the query dispatcher with the appropriate commands,
writen a modern GUI to interact with the
"expect" layer, and piped them to the DBhost
over a socket.

If this is what you want, then "expect" is the
way to go.

Depends what you're tryin to do. If you want to effectively use a remote keyboard, you need to photo-couple to the keyboard using opto-isolators or cmos. It's easy with opto-isolators soldered across the keys on the pcb and the capacitance problems then disappear allowing a longish link between the real keyboard & dummy.
You can then use software like John Hnidec's CCM to generate any combination of keystrokes from a single keypress. Try searching flight sim sites for 'Control Command Module' if this is what you want to do.
As this is a little OT, contact me off list if you want any more on this.
