The problem is that not all USB serial (RS-232) adapters are well behaved.
In addition, some laptops with built-in serial ports are actually an
internal USB to RS-232 converter.
Case in point - I work with a wide assortment of telecom devices (Avaya PBX
gear, Cisco routers and switches, and some really esoteric stuff). I also
interface to a Clifford alarm, Uniden scanner, and Kantronics KAM-XL - plus
programming interfaces for Kenwood and Icom radios.
I needed a laptop that would talk to all of these. Plus I wanted a Cardbus
(PCMCIA) slot to use an EVDO device (Sierra AC595 for Sprint).
One of the local vendor techs has a Sony VAIO that his employer got for him.
It has an RS-232 port. Several of the vendor-specific programs don't like
the RS-232 port in it. Turns out that it is internally a USB to RS-232
I have a Toshiba Tecra A9-S9015X. It runs XP just like his VAIO, but
everything I have - including the same vendor-specific software - works very
well with it. It is a real RS-232 port.
The Toshiba Tecra A9-S9013 is a similar system, but came with Vista
installed. MS changed the way serial ports work under Vista, and the
Clifford alarm software does not work under Vista. Put XP on that A9-S9013
(or buy an A9-S9013X) and poof - everything works.
I had a chance to speak with the Toshiba program manager for laptops at CES
in January. They appreciated hearing first-hand that the RS-232 port is not
a waste of time. It gives them an edge, the only other systems that really
have real ports are Dells, and the cost is higher.
I have been impressed with the quality, and I have put mine through rough
use. I bought matching A9-S9015x units for my family.
Here is a review I wrote. I really recommend the Tecra A9 units.
