Virtual Modem allows any modem communications applications to interact via LAN or the Internet. Application "dials" remote IP address instead of making a dial-direct call using hardware modem. Moreover, it looks as if the application worked with hardware modem. But in fact, a hardware modem is not used.
Common Solution
Usually hardware modems are used to connect communications applications over standard phone lines.
Drawbacks of Common Solution
Common solution has some drawbacks:
Phone line and modem hardware are required.
You need a phone line and a modem beside each computer from which you want to establish modem connection.
Phone call charges.
You have to pay for each phone call. It's even worse if you make international phone calls.
Busy phone line.
You cannot use your phone line for other purposes while using modem connection.
Unreliability of phone connection.
Besides phone connections are not reliable, they are low-speed.
New Solution by FabulaTech
Virtual Modem allows you to create and use virtual modems instead of hardware modems. At that network connection (LAN or the Internet) is used for data exchange instead of phone lines.
1) Application A on local computer "makes a call" using virtual modem #1.
2) Virtual modem #1 on local computer connects to virtual modem #2 on remote computer over the network.
3) Virtual modem #2 accepts network connection and initiate "incoming call" for application B.
4) Application B reacts on "incoming call" from virtual modem #2 as if it was real incoming call initiated by hardware modem.
And now, applications exchange data as if they were connected via physical phone lines.
Virtual modems look like hardware modems for all communications applications.
FabulaTech Solution Benefits
Automatically network-enables modem communications applications without software changes.
There are no charges for phone calls (you pay only for Internet access).
You need neither phone line nor modem.
Speed is far higher then hardware modems have.
Location-independent. Virtual Modem can be used anywhere in the world where Internet access is available.
You can limit network access to your virtual modem using any firewall software.
Target Groups
Virtual Modem allows you to use network connection (LAN or the Internet) instead of hardware modems without making changes in existing communications software.
Virtual Modem is successfully used in such spheres as financial systems, credit card transaction, legal information database access, real estate information systems, device control and data acquisition, building automation, security systems.
Virtual Modem Features
Replace hardware modems with pure software.
The program allows any modem communications applications to interact via LAN or the Internet. Application "dials" remote IP address instead of making a dial-direct call.
No charges for phone calls.
From now you do not have to pay for each phone call (especially for international phone calls).
Location-independent.
Virtual modem can be used anywhere in the world where Internet access is available.
Full list of features
General
Virtual modems look and work like real hardware modems
Applications use virtual modems directly from virtual serial ports or through TAPI
Virtual Modem can originate or answer TCP connections with any other device, including computers running another copy of the Virtual Modem.
Up to 256 virtual modems can be created
Virtual modems are compatible with fax software
Virtual modems work with IP Fax Machines
Virtual modems can "dial" to remote virtual modems using IP address (or computer name) and TCP-port instead of phone number
Virtual modems can accept "incoming calls" from other virtual modems
Phone book. It allows you to simplify switch to virtual modems from hardware modems. You can specify telephone number corresponding to IP address (or computer name) and TCP-port of remote virtual modems.
Once created virtual modems are operable at each system startup (even prior to user login)
Compatibility
Support of main AT commands
Support of main S-registers
User interface
User-friendly program interface
Hot virtual modem creation and removal, without computer reboot
