Look at it this way, if you have a USB port you can easily add a RS232
adapter. But what do you do when all you have is a RS232 port?

Use an NMEA multiplexer.

Not really. Only in the consumer market. 99% of the industrial computers
have serial ports because 99% of the industrial devices that need to
communicate have a serial port.

I assume were talking about laptops, you can easily add anything needed
to any PCI bus PC. On laptops most of the non-USB models will have
PCMCIA so you can add a PCMCIA dual port USB port adapter.

I think the laptops that did not have PCMCIA are all dead or in museums
by now. But I'm also sure that there is someone out there still using
them. Probably trying to get linux running on them. :)

I got this story from a Dell laptop owner that I don't know very well,
so I can't vouch for it. He said that his new Dell has, in place of
PCMCIA, something called Dell Express. It sounds and looks a whole
lot like PCMCIA with an arbitrary form factor change to make it
proprietary. He had purchased a PCMCIA cellular modem and data plan
from T-Mobile and discovered the card didn't fit. When he called
Dell, they said that it was up to the cell company to support the
obviously superior Dell proprietary format. When he called T-Mobile,
they said they'd never heard of Dell Express and weren't interested in
it either.

I remember Dell pulling this stuff back in the day with proprietary
video card slots, so it doesn't sound entirely unlikely. Caveat
Emptor.

Exactly at the point in time when he should have packaged it back up and

Just curious, if you have one of the 4 USB units, does it have enough
power at the ports to drive 4 USB-powered devices at the same time? I
have a USB-powered hard drive; it works fine on some laptops, not at
all on most of them. When I use an external power supply everything
is fine.

I'm using my US Modular 2.2GB USB pocket hard drive from the USB port on
the Gateway with no problems. The drive is $53 from any WalMart
electronics department. It looks like a miniature silver hand warmer with
the silver cap on the USB plug. It also comes with a 2' USB extension
cable in case you have trouble plugging the drive directly into the port on
your system. It plugs direct to any port in the side of the Gateway. It
uses quite a bit of power in my application, watching a new movie at my
breakfast diner, for instance. It gets very warm under continuous access
like this, but I've never heard a complaint from the big 15" notebook's
battery pack.

My 400GB external USB hard drive gets its power from an AC power brick, not
the USB port. Its USB port is the square one without the power drain. I
wouldn't expect any computer to run the 400GB big hard drive and all those
LEDs and cooling fan. USB doesn't have that kind of power output.
