I should also note with this usbserial adapter, this MCT serial adapter has
blinking red & green lights denoting RX/TX.

If I'm not mistaken, I get four series of green (LINK) and red (RX) lights in
what looks like an attempt to communicate with the DB9/COM linked device. 
Green is always lit until the red TX/RX lights light, so I see a green light,
then a red RX light and then green link light blink.  This occurs four times,
until the above noted error occurs, and likely a timeout error.  (The COM/DB9
device is probably being probed with an incorrect request.  Wine might be only
configured to communicate with other computers running a full terminal, already
transmitting data?)

The lights being green (LINK), red (TX), red (RX).  I don't think I see the TX
light lighting up, as this might be the light for when the DB9/COM connected
device transfers data downward.  I'm guessing, WINE is yet to be configured to
deal with common RX/TX requests as noted above.

The only other DB9/COM device I have is a GPS hockey puck antenna, for which I
do not currently have a desktop 12VDC power supply yet and I know this device
constantly outputs GPS data not likely requiring any request packet to initiate
the data from being sent out.  I do have another computer to run a terminal
(ie. mintty), but hasn't been setup configured in this method for quite
sometime.
