perl net-dialup To send alphanumeric pages to a pager, if an email gateway is unavailable or undesirable, software is needed to control a modem which will dial a "Paging Central", and deliver the pages using an ASCII delivery system known as "TAP". Sendpage implements all aspects of this type of software, including an SNPP client, an SNPP server, a queuing engine, a modem control engine, a TAP communication system, and an email notification system.
