Hook the Xmit to the Rcv, use a terminal emulator to send text, and see
if what you type is echoed.
If the C# program is putting out any characters when it starts, can you
see them in a terminal emulator? You may have the baud rate wrong. You
could also experiment with this with the Arduino by cycling through a
range of baud rates and seeing if any of them get a response.

From the C# It looks like I should just have to send 13 bytes starting
with 33 (which is ASCII for !).
Actually you need to send 14 bytes (rowCount + 1, and rowCount always
returns 13) so maybe it would help to change the last write to a writeln?
And I know you don't want to change the C# code but isn't your array
one byte too small? Aren't you reading 14 bytes into a 14 byte array?
Don't you need room for a terminating character?
