I'll have to see if I can find an adapter like that.

Is this what you mean:

What I use is "PuTTY for Linux", which is really handy because you can 
setup a profile and assign it device /dev/ttyS0 along with the speed, etc...
My laptop does not have a serial port, so I use a USB to 9pin Serial 
adapter, and when I plug it in, I check dmesg which tells me it is 
ttyUSB0 and I setup my profile accordingly.  Also, PuTTY for Linux, has 
the same look and feel as the version for Windows that we all know and 
love.  :-)
