[TenTec] OT: USB to Serial

For anyone who might be interested, here's an update: I purchased a 
Syba PCI-E 2 port serial card and installed it. The polling behavior 
is not evident on either port of the card. It remains evident when I 
use any USB-to-serial adapter, just as before.

A very strange problem that I do not understand. The on-board COM 
port is usually (but not always) a true serial port with a 16C550 
UART as part of the Southbridge chip. However, on this board, that 
may not be the case.

Regardless, I have a work-around!
