The Null-modem emulator allows you to create an unlimited number of virtual COM portpairs and use any pair to connect one COM port based application to another.Each COM port pair provides two COM ports. The output to one port is the input from otherport and vice versa.
The Null-modem emulator can be used to provide serial interface for device emulators.In this case the device emulation program uses one port of the pair andthe other port can be used by Windows or DOS application thatrequires a COM port to communicate with the device.For example, to send/receive faxes over IP you can connect WindowsFax application to t38modem (T38FAX Pseudo Modem ,part of the t38modem project ) via virtual COM port pair.
Block-oriented terminal emulators. Emulators for block-oriented terminals, primarily IBM 3270, but also IBM 5250 and other non-IBM terminals. Coax/Twinax connected. These terminal emulators are used to replace terminals attached to a host or terminal controller via a coaxial cable (coax) or twinaxial cabling (twinax). The Android emulator itself supports this feature, I see people use 'emulator -qemu -serial COM1' on Windows PC. Or 'emulatro -qemu -serial /dev/ttyS0' on Linux PC. I have not tried it by myself yet, but that is the way in the big picture.
The Null-modem emulator can be used to provide serial interface for COM port redirectors.For example, with the com2tcp (COM port to TCP redirector,part of the com0com project ) you can communicate via serial interface with the TCP/IP servers.If you feel that com2tcp is what you need but can't find some required features (for example RFC 2217 support) then try use hub4com instead.
With the hub4com (HUB for communications,part of the com0com project ) it is possible to handle data and signals from a single serial device by a number of differentapplications (for example, several applications can share data from one GPS device).It's also possible to use the real serial ports of remote computer like if they exist on a local computer.
You can find more information inUsing com0com and com2tcp,ReadMe.txt for com0com,ReadMe.txt for com2tcp,ReadMe.txt for hub4comand onSourceForge Projectpage.
Alternatively, you can use Virtual Serial Port Driver by Eltima Software. It allows creating a large number of virtual COM ports and gives you great possibility to emulate serial port behaviour fully. Virtual Serial Port Driver provides flexible port creation, management, and removal, allows testing the software, supports control lines and high speed of data transfer with virtual port.
- Create any number of virtual COM ports
- Complete real ports settings emulation
- Manage all signal lines
- instantaneous ports creation lets working with them even before PnP manager detects the newly added ports;
- full supports of Windows 10

What sets Kermit 95 apart from other Windows communications packages?Its unique combination of security options, connection methods, protocols,character-sets, customizability, and scriptability, plus the sheer number andaccuracy of its terminal emulations. And we don't only 'do Windows' -- wealso provide compatible software for Linux, FreeBSD, OpenBSD, Solaris, AIX,HP-UX, VMS, and lots of other platforms. Learnthe Kermit command and scripting language once, use it on many kinds ofconnections and on many kinds of computers and operating systems:past, present, and future.
Kermit 95 is used all over the world in the academic, government,corporate, and nonprofit sectors.In the private sector, K95 is a favorite of consultants, systemintegrators, and makers of high-tech equipment, who bundle it with theirproducts or services. In the health-care industry, it's widely used forinsurance claim submission as well as in hospital information systems,laboratories, and medical devices; in the retail market, it's used forinventory, POS, and EDI applications; in libraries for catalog access andback-office work; in any large organization, it's a handy network monitoringand management tool. It's popular internationally for its comprehensivecharacter-set support. In every sector, its security features make it idealfor remote maintenance of secure websites and for any critical or sensitivetext-based applications -- as well as for such simple tasks as reading your e-mail withoutcatching a virus.
FEATURES
[ DOWNLOAD ][ Order ][ Top ][ Home ]Kermit 95 is Year-2000 readyand Euro compatible. It has two major components:
THE DIALER| The graphical Dialer configures and launchesall your connections (dialed or network, secure or clear-text, terminal orFTP) by means of menus, buttons, and dialog boxes so you don't have to dealwith complicated initialization files, macro definitions, commands, or'syntax' of any kind. The Dialer can configure as many different connectionsas you want, and can manage multiple simultaneous active connections. Foradded convenience, the Dialer can create desktop or Start-menu shortcuts foryour most frequently used connections. |
| The actual work -- communications, file transfer, scripting, etc -- isdone by the K95.EXE program, similar to its cousins onUNIX,VMS, andMS-DOS,which is normally (but need not be) launched from the Dialer pushbutton-styleto make each of your connections automatically with all the appropriatesettings and desired customizations. The graphical Dialer removes the need tointeract directly with the command prompt in most cases. Yet all the commandsare there in case you need them . . . or if you want to script them. Thus theDialer configures, organizes, launches, and manages your connections, and K95does all the real work. |
Beginning with Version 2.0, the connection engine comes in two forms:Graphical User Interface (GUI), K95G.EXE(Windows only, notOS/2), and Console, K95.EXE. Previous releases were availableonly in a Console version. For a detailed description of the new GUI version,CLICK HERE.
