A similar driver, the Virtual Null Modem Cable, is available at Phil Covington's project page:

• http://developer.berlios.de/projects/n8vbvcomdriver/

The driver emulates two serial ports ( for example, COM5 and COM6 ) and provides the "bridge" between them, which is equivalent to a null-modem cable. The baudrate settings DO NOT matter.

MixW emulates KISS TNC (since MixW v.2.04).

Notice that DOS-box programs usually support COM1, COM2, COM3 and COM4 only, i.e. you will have to re-configure the driver.

This mode has been tested with JNOS 110i in DOS box in 2400/9600 baud mode, and also with UI-View V2.36 in 1200 baud mode.

MixW uses another program as a TNC.

Some programs ( for example, MMTTY ) can emulate a TNC on the specified port. Then MixW can use them like if they were real hardware TNCs.

To use MMTTY as a TNC,

1. In MixW, go to Configure - TNC settings menu and set up the port number.
   
   

2. In MixW, go to Mode - TNC modes settings menu and define the new mode. Define several  macros for this TNC mode ( mmtty.mc ):
   
   Macro: OnStartMode
   Label: start mode
   Text: <HIDETEXT><AUDIOFQ:1000><SHIFT:170><CR><LF>RTTY<CR><LF><SHOWTEXT>
   
   Macro: TX
   Label: goto tx
   Text: <HIDETEXT><CTRL-C>T<SHOWTEXT>
   
   Macro: RX
   Label: goto rx
   Text: <HIDETEXT><CTRL-C>E<SHOWTEXT>
   
   Macro: RXANDCLEAR
   Label: not supported, map to <RX>
   Text: <RX>
   
   

3. In MMTTY, go to Options - Setup TNC emulation menu:
   
   Choose a COM port,
   set TNC type = KAM,
   set Local echo = After Sending.

MixW 2 (starting with version 2.02) supports TCP/IP over AX.25 (datagram mode).

This means that you can use standard Windows' software to communicate with other TCP/IP systems ( UNIX/Linux, AGW Packet Engine, Flexnet, MixW 2 ) over a VHF radio channel.

Please set soundcard samplerate to 22050 for 4800 or 9600-baud packet, and 44100 for 19200-baud packet.

Download virtual network adapter drivers (unzip to the separate folder and see ReadMe.txt file for installation instructions):

These drivers have been tested with Windows 98 SE 4.10.2183A, Windows 2000 5.00.2195 SP2, Windows XP 5.1.2600, Windows NT 4.0 1381 SP6.

There are several hints to help run TCP/IP with MixW:

• Make sure that your station "sees" the other station (and vice versa) and is able to transmit and receive packets. Try to establish a usual (i.e. not TCP/IP) connection with the other station. 
  
• Make sure that the driver is installed OK and Windows sees it. Use Windows' IPCONFIG.EXE program to check this.
  
• Set up the IP address and subnet mask properly. If you are planning to connect two computers with MixW, you can enter arbitrary IP addresses. But connecting to an existing packet network usually requires using a registered IP address of AMPR network, which can be obtained from the local AMPR coordinator (see http://www.ampr.org/ for details).
  
• Make sure that MixW can see the driver: when MixW is started, you should see "MixW virtual network adapter is running" message at the status bar.
  
• Set up the IP routing using Windows' ROUTE.EXE program, if needed. If you have another network card (or modem) installed, you can define which network card Windows will use to connect to the specified servers. This is a very important part of the setup.

 To use a KISS TNC with these drivers. 

Try our new Ax25Inet program ( MixW is not needed in this case ).

Download Ax25Inet version 1.3.

Unzip the files in a separate directory, then run Ax25Inet.exe ( virtual network adapter driver should be installed ).

No help file yet (sorry), but the interface and settings should be OK for an experienced KISS TNC user.

To translate the program interface to another language:
1) Copy Russian.lng to XXXX.lng ( where XXXX is the name of your language ).
2) Edit XXXX.lng with a text editor, replacing text after the ' = ' sign.
