The one I have has 7 bicolour LEDs, monitoring TxD, RxD, RTS, CTS, DSR, 
DTR and CD. I find it very handy fo checking an unknown serial port (is 
it DTE or DCE), seeing if data is flowing, etc. 

I have other RS232 test equipment too, up to a Tekky datacoms tester, but 
I still normally grab this little 'christmas tree' [1] tester first. 
There's no way I can set it up wrongly for a state. Of course sometimes I 
do need the more adcanced testers, but not very often

[1] That's what they tend to be called over here, because of the red and 
green flashing lights ;-)
