About Vmodem (Virtual modem)
Vmodem is a feature of the IOLAN, which provides “modem like” communication between
two IOLAN units on a network. This feature behaves like two modems connected across a
telephone line.
Typically, you use the Vmodem feature when you have multiple devices communicating with
a central site.
Vmodem allows you to achieve this using a single IOLAN unit at each end of the network
without having to use multiple modems.
You use Vmodem because you want to avoid having to use multiple modems with the
associated costs of calls and connections.
You use this feature by logging into the IOLAN via a terminal or telnet. You then enable and
configure the Vmodem feature on the ports you want to use. You then connect your remote
devices to the Vmodem ports on the IOLAN units.
