PS/2 scanner on COM port using adapter

Hi

This is a somewhat odd issue....

A client wants to use a hand held scanner, as by their standard using
a PS/2 plug. Not replaceable if anyone has that idea. Customer's
standard.

In order to get data from the scanner only and not mixed with the
keyboard, so we were wondering, is it possbile to use a PS/2 to COM
adapter....
It works with a USB adapter, but then we dont know whether someone
typed it or got it from the scanner.

First extra power is needed, this is simple. The adapter does not give
much and the scanner needs 100mA.

Next, how does this work - the adapter simply translates the PS/2
synchronized data to async data?
In that case I should be able to read at 1200 baud, 7 bits etc.
So far it has not been possible.

Now, has anyone tried such tricks before?
It is possible to use PS/2 to COM adapter and read from the comport,
such as a mouse or keyboard?
