No.... modems like the US Robotics V.Everything can be programmed with a call-back feature. You dial up the modem, it askes you for a password, you supply the password, and it then hangs up on you, picks up the line, and calls back a configured phone number. You program the modem to call YOU back on a number which has a modem connected, and waiting for an inbound data call..... your modem answers, and you are connected. You then negotiate access to the server (name/passwd) over the serial link. If the remote is connected to the the target serial port consol, you have a pretty hack-proof (nothing is really hack-proof) console access. The modem will only call a pre-set number, so even if someone got your password, the modem would only call you, not the hacker.
