An alternate to USB/Serial converter?

[David Christ]

The slots/ports on laptops seem to be an ever changing thing, but has
anyone tried to use something like these to avoid the USB converter?

Express card/34

PCMCIA

These are only two examples of what is out there.  I suspect that
card slots are disappearing off laptops these days too.  However one
might with a little searching find a laptop either new or used with
such a port .  I know that Apple and HP are currently selling laptops
with express card slots.  Both can run windows.

Yes

I have used a lot of the PCMCIA ones on my DELL/IBM Thinkpad laptops over
the last 10 years. The laptops come with one serial port, but I use the
PCMCIA card to give me one or 2 more for FSK, rotator control, PA control
etc

I use the socket communications Inc versions, see
http://www.socketserial.com/support/Cards/CFandPC%20Card%20Datasheet.pdf.
Some of their older version single and dual PCMCIA serial cards (circa 1997)
have been going for as little as $5 each recently

Yes, use them all the time and they work just like built in serial
ports. Both card slots are still on laptops being sold though the shift
is to the express card format it seems. 73, Tom n4zpt
