Its great that you added status outlets. How about having just one  
status outlet?  Then it would output like: [port 3(, [dsr 1(, [cts 0 
(.  You can then get the individual outlets easily by using a [route  
port dsr cts].

Then it would also be very easy to add more status information  
without breaking backwards compatibility.  It would be nice to have  
things like connection status [open 1(, [baud 9600(, [devicename /dev/ 
ttyS(, [parity 2(, [stopbit 1(, [bits 8(, etc.

I've done it this way with [hid] and [usbhid] and it works quite  
well.  It would be nice to have [comport] have a similar interface.
