Virtual Modem

Virtual Modem PRO works for every automation system that collects data from remote hosts using modem and telephone line. Virtual Modem PRO creates virtual com ports and attaches virtual modems to them, which work in the same way as real ones (support Hayes AT commands), however use TCP/IP protocol to connect to remote host. This gives better speed and reliability of transmitted data as well as up to 255 modems that can be created in any system.

To emulate null-modem connection Virtual Null Modem can be effectively used. The program emulates one or more couples of RS-232 serial ports connected via virtual null-modem cable. It is possible to create the unlimited couples of VSP on a single PC without additional hardware and connect them in any sequence using virtual null-modem cable. Usually you need to use virtual null-modem when you have two applications to be connected via serial ports.
