Title:
Determine dial tone?
I'm looking for a way to determine if a dial tone can be gotten from a modem. I have a modem hooked to a Windows server and sometimes the line goes down or the modem is unavailable for a variety of reasons and I'd like to programmatically know this, presumably by taking the modem off hook and detecting a dial tone or some other indication that the modem is turned on and able to get a dial tone.
Anyone ever done this? Thanks in advance.
Gary
