I think it depends on whether you are using .net 2.0 or not. I think on 
.net 2.0 the SerialPort classes are included on the microsoft framework 
(someone correct me if I am wrong). I have a package I got from 
somewhere long time ago (made by MS) that implemented System.IO.Ports 
for .net 1.0/1.1, that library had almost the same API as .net 2.0 and 
mono, so I made a few modification to it so it would work on both Linux 
and Windows without the need of a recompile. The only problem was that 
on mono it seemed like the System.IO.Ports namespace is in System.dll 
and on windows for me it was on SerialPort.dll so on Linux I do 
something crazy which people are gonna laugh at, I make a symbolic link 
of SerialPort.dll to System.dll and it works fine. If mono did some more 
serious assembly checks it wouldn't work, specially since all my 
assemblies are signed!
On both reading and writing from the serial port is really easy, I use 
pretty much the same code. Mono hasn't implemented everything yet, like 
you can't receive SerialPort events yet like you can on windows, a lot 
of the Write methods were missing but enough functionality is there to 
make it usable. I have not looked at the Mono serial ports classes in 
several months so this may have changed a lot.

Hope that helped.
