The Serial Utility waits for serial activity on a serial port/speed specified by you. For example, COM1: 38400. After that, any data from the serial port is routinely bundled into a configurable e-mail format and sent via SMTP to whomever you choose. If the data can't be sent to the mail server immediately, it is buffered until the connection to the server/Internet is restored. Great for remote monitoring of embedded devices with serial debug outputs and reporting to your ISP when your CABLE MODEM reboots. Unregistered versions will work for 1 hour per launch.
