[TRLog] Serial card question

[Mark Beckwith]

Quick question.  I have an old card which does "2 serial ports."  There is a
big empty socket on it.  Does this mean that to use serial port #2 I have to
buy/scrounge a chip?

The instructions have a chip number in parenthesis in that spot on the board
but nothing to the effect of "this board really only does one serial port
out of the box; if you want to use 2 you have to get the missing chip?"

Anyone been-here-done-this?
