By "normal phone calls", do you mean voice? If you do,
no, it isn't. Dependig on your modem, there might be a command
to make the thing answer in voice mode, but ATA is not going to do it.
After a normal modem answers a call, it tries to negotiate a data
connection with a remote modem, then if it is successful (I think) sends
the report CONNECTED to the serial port. If not, it sends NO CARRIER
and hangs up.
