 * Getting the baud rate is different on the two systems.
 * In either case, a baud rate of 0 hangs up the phone.
 * Since things are often initialized to 0, getting the phone
 * hung up on you is a common result of a bug in your program.
 * This is not very friendly, so if the baud rate is 0, we
 * assume we're doing a reset_xx_mode with no def_xx_mode, and
 * just don't do anything.
