Or the Windows API... (yep, ended up using API calls to get serial port and WinSock interface - most of the details are incorporated into their respective class libraries). Of course, since I was using such low-level access to serial port, I ended up having to deal with messy details of fiddling with modem initialization strings on a per-installation basis. Actual dial command is the easy part, the hard part is modem initialization string -- due to their brand and model-specific nature (or more specifically, the chipset of firmware version). Usually to get a reliable and predictable connection, I usually have to "dumb down" the modem by turning off features such as data compression and/or error detection/correction -- something that modems may agree on being able to do, but not always agree on particular method (it's sort of like two folks speaking English -- if one uses American English and the other British English, most of the time they're able to understand each other, but there are occasions where they might not understand each other).
