Virtual Modem PRO creates software virtual IP-modems and maps them to virtual serial ports in your operating system. Virtual modems fully emulate standard hardware modems. The main difference between standard modems and the virtual ones, created by Virtual Modem PRO, is that instead of using conventional telephone line they use Ethernet network, including Internet, VLAN, VPN, etc. Generally, standard modems are connected to the computer via serial ports (COM1/COM2 or » Lees meer... |  |

Virtual Modem PRO creates software virtual IP-modems and maps them to virtual serial ports in your operating system. Virtual modems fully emulate standard hardware modems. The main difference between standard modems and the virtual ones, created by Virtual Modem PRO, is that instead of using conventional telephone line they use Ethernet network, including Internet, VLAN, VPN, etc. Generally, standard modems are connected to the computer via serial ports (COM1/COM2 or COM3/COM4). Virtual modems, on the other hand, use virtual serial ports that are complete copies of real serial ports, and can be accessed and utilized in the usual way. Among the main advantages of using virtual modems are the speed and reliability of the transmitted data (since it uses fast Ethernet network and reliable TCP/IP protocol) as well as a considerable number (up to 255) of modems that can be created in any system.
Who can benefit from using virtual
modems?
Every automation system that collects data from
the remote hosts using modem and telephone line
can greatly benefit from implementing Virtual Modem PRO.
Among these are manufacturing/warehouse data acquisition systems, fiscal/data
transfers in a banking system, retail management, etc.
For example, your bank has invested a huge
lump of money and connected all its branches
into a Virtual Private Network by fiber optic
cable. However, the data transfer system still uses
legacy application and conventional telephone line.
How virtual modems work?
Virtual Modem PRO uses virtual serial ports technology which fully emulates real serial ports and duplicates all their functionality. This innovative technology allows selecting any available protocol and opens a wide range of new creative opportunities for derived applications. Virtual modem attached to a virtual serial port, works in the same way as the real one (supports Hayes AT commands), however it uses TCP/IP protocol to establish connection to remote host. To create such connection 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. Every instance of the virtual modem could be configured to be server or client at any time depending whether you want to generate outgoing call or accept it (same as the standard modems). In addition, you may specify the TCP port which will be used to establish the link and IP-address or hostname of the server to connect to.
In order to establish such client-server connection you should install and set up Virtual Modem PRO on both ends. Single license allows you to install and use Virtual Modem PRO on two computers in a network. OEM license allows you not only to install the software on any number of computers and embed the technology into your own software, but also extend and modify Virtual Modem PRO (Source Code License may be required).

- Fixed: Incorrect behavior while closing connection
- All major software fax applications are supported (Microsoft Fax/Ventafax/SnappyFax 2000/Mighty Fax)
Full features list:
- Fully emulates Fax Class 1 modems - New!
- Send faxes to any place on the Internet using virtual modems - New!
- All major software fax applications are supported (Microsoft Fax/Ventafax/SnappyFax 2000/Mighty Fax) - New!
- 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
- Virtual link is much more reliable than common physical link
- 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!
