You have not put the tty in raw mode, and so the OS's tty layer is translating CR into NL, thus the apparent double NL. The preceeding double NL comes from the "ATZ\r\n" with is the modem echoing your typing (well, your write) for you. You want to turn off the crnl translation (see stty and termios manual entries) and probably turn of the modem's echo with an ATE0 command.
