Virtual Modem PRO is a software that emulates hardware modems by creating virtual IP-modems and mapping them to virtual serial ports. It uses Ethernet network/ VLAN/VPN as an alternative to conventional telephone lines.

One exciting new feature of Virtual Modem PRO is that it can not only emulate Fax Class 1 modems, but also send faxes to any place on the Internet using virtual modems. This means that all major software fax applications are supported (Microsoft Fax/Ventafax/SnappyFax 2000/Mighty Fax), and you can set up and use Windows Fax service or any third-party application to send/receive faxes to any host on the Internet without hardware modems.
This takes the software's functionality to a whole new level and can save you money on purchasing fax machines and sending long-distance faxes. The main difference between Virtual Modem PRO and conventional modems is that it uses Ethernet networks, including the Internet, VLAN, VPN, etc. Virtual modems are connected to the computer via serial ports (COM1/COM2, or virtual serial ports that are complete copies of real serial ports).
Virtual Modem PRO also boasts high speed and reliability of transmitted data. It uses a fast Ethernet network and reliable TCP/IP protocol, making it an ideal choice for automation systems that collect data from remote hosts using modems and telephone lines. These systems include manufacturing/warehouse DAQ systems, fiscal/data transfers in a banking system, and retail management, among others.
To set up Virtual Modem PRO, the first virtual modem (local host) should be configured as a TCP/IP server that listens to incoming connections while the other one (remote host) should be configured as a client to initiate the call. This ensures a seamless connection and helps duplicate all the functionality of real serial ports.
In summary, Virtual Modem PRO 3.0 is a highly functional software that can emulate standard hardware modems, send faxes to any place on the Internet, and offer high speeds and reliability of transmitted data. It is also highly customizable, supporting up to 255 modems in any system.
Version 3.0:
1. Fully emulates Fax Class 1 modems
2. Send faxes to any place on the Internet using virtual modems
3. All major software fax applications are supported (Microsoft Fax/Ventafax/SnappyFax 2000/Mighty Fax)
Version 2.0:
Create up to 255 virtual modems in your system;
Virtual Modems are absolutely the same copies of real ones - other applications will never see the difference between hardware and virtual modems;
Hayes ("AT" commands) compatible;
Standard modem S-registers are supported;
Link between Virtual Modems over the TCP/IP line is much faster than real null-modem cable connection and solely depends on your processor speed. Average transfer speed is about 35-40 Kbytes/sec
Automatic virtual ports and modems creation during system boot (prior to user login);
User friendly GUI and on-the-fly help. It is very easy to configure Virtual Modem PRO as ISP dial-up connection.
