On the old 1900 switches the console port is not a RJ-45, but a COM-port. I
have tried to but RJ-45/DB9 adapter on both sides of the rollover cable, but
I don't get any connection. I have also tried the "new" rollover with DB9
on one side and RJ-45 on the other + adapter on one side, but the result is
the same (of course).

In fact there is som sort of information going through the cable. I get
this on the screen: ATQ0H00Z

Is there an old type of cable that has DB9 on both sides? Or is it other
settings on the Hyper Terminal (Other than the usual 9600/8/N/1)

I have tested the console cable and connectors on a router and they work
fine.

Yes. Covered here many times. Look for it on groups.google.com

http://www.conserver.com/consoles/iolancons.html includes the following
__________________________________________________ _____________
Note: Some Cisco 1900-series switches use a DB-9 console connection, instead
of the RJ-45 connector. Some of these devices require a DCD signal on DB-9
pin 1, while other versions of the 1900 do not want a DCD signal applied to
DB-9 pin 1.

If the Cisco 1900 you have attached to is spewing AT modem commands out
the port, you have a problem. If you are using a stock adapter (with the DCD
signal) you will need to open the adapter, and remove the wire from pin 1 of
the DB-9 and then label the adapter so you know it has been modified. (If
you are seeing the AT commands with a modified adapter install, get an
unmodified adapter.
