USB to RS232 converter
On the surface this might appear to be an easy solution (about as easy as
you typed and sent it), but USB to RS232 converters come with OEM
installable drivers with confusing or no interfacing APIs.
APIs? I suppose if you don't want the virtual serial port to appear
anywhere you might want some other kind of API, but otherwise you just
use the ones in the OS for accessing seial ports.
Plus, if your
"black box" is to become a product, it means you have to purchase,
distribute and explain how to install these OEM drivers onto an end users
laptop. Drivers and hardware that might not be supported by the OEM
throughout the life of your product.
So what are the solutions requiring nothing be installed? An ethernet
port and Telnet? Some hideous hack where the device appears a USB Mass
Storage device even though it isn't? Not very user-friendly and I expect
laptops will have USB ports for longer than ethernet ports (which I
could see being eliminated from some models with the increasing
prevalence and speed of WiFi).
