Computer with PS2 only to connect to RS232 DB9 device?

Hello,

I was wondering if someone knows how to do this. There are adapters from
PS2>DB9 normally intended for mice, but I have a reverse situation:

I need to connect a RS232 device (specialized digital modem) to a laptop
only equipped with PS2 port.

Normally the modem would use its proprietary software which uses COM1 on
normally present DB9 on the PC and everything works.

However in this case there is no DB9 on my laptop. QQ:

1. Is there a way to buil some kind of adaptor to translate computer PS2
port to RS232 DB9?

2. If 1st is positive- can I then define the PS2 in this laptop to act
as COM1 and communicate via this adapter with external RS232 device?

Thanks for any clues, Regards M

If it's a new laptop it should have a USB port. The Rat Shack sells USB
to RS-232 adapters that seem to work just fine.

If the USB to RS-232 adapter doesn't work then see if you can find a
UART on a PCMCIA card.

Hi Tim

Thanks , this was my thought too.

However- the whole situation is somewhat limited- my friend is on a boat in
Carribean in with no access to almost anything. But he does have DB9 and RS232
connectors and soldering iron and I hoped maybe I could figure our something
to be put from wires alone- is this definitely not an option, (I mean PS2 to
RS232) ?

This definitely not an option. The voltage levels, sync methods,
and protocolsn don't match. Perhaps that fellow in the movie who
was able to hack into a UFO with a Macintosh could do this, but
your friend on the boat needs to get a USP to RS232 adapter.

It is never correct to post something to sci.electronics.design
and sci.electronics.misc. *.misc groups are for things that
don't fit in any of the other groups.
