Hi, everybody!
I've an app that communicates with an hardware via RS-232.
A problem arises using a modem connection, like this:

PC <-(RS232)-> Modem ... Modem <-(RS232)-> HW

My primary goal is to query line status to check when link drops down.
I've take a look to GetCommModemStatus, WaitCommEvent and SetCommMask 
WinApi functions,but I don't know which signal must be observed.

Answers and examples will be warmfully appreciated.

TIA.

Davide.
