Aihe: [ct-user] Getting Inet DX Spots into CT, on single PC, only 1 RS 232


> 
> Hello,
> 
> This is IK4VYX, Fabrizio: the developer of DXTelnet.
> 
> Here is how I get internet DX Spots from any Internet cluster
> directly into CT, all in a single PC with only one (I repeat: ONLY ONE) 
> serial port.
> CT must be run under Windows in a DOS shell and the free serial port
> must be configured as a CT's TNC port.
> 
> Requirements:
> A Windows PC connected to Internet 
> (All windows family is OK, except NT and 2000; I don't know about Win ME)
> At least 1 free serial port
> A DB female dummy connector with some shortened pins 
> (in case of  9 pin serial port, shortened pins are 2-3, 4-6-8)
> (in case of 25 pin serial port, shortened pins are 2-3, 5-6-20) 
> this dummy connector to be plugged into CT's TNC port 
> (of course no TNC must be connected).
> 
> The software I used is, of course, DXTelnet which allows data exchange via file.
> For this purpose I made a TSR which gets the data from the TXT 
> exchange file created by DXTelnet and sends the spots as they arrive
> to the I/O address of the CT's TNC port (using direct I/O address will
> prevent from serial port conflicts, that's why only one serial port is
> enough in this case; direct I/O is not alowed in NT and 2000, that's why it
> wont work there)
> Data are written byte by byte directly on the I/O address of the UART's TX
> register, the loopback connector then sends the same data to the RX register
> so that CT can read the spots.
> 
> Operation:
> I plug the dummy connector on the CT's serial port.
> I run DXTelnet and I enable the file exchange link.
> I connect DXTelnet to the CQDX-IRC site, which is the one which carries
> the biggest number of DX spots.
> I start a DOS session and run my TSR (its name is DXT2LOG)
> At the same DOS prompt I start Comtsr2 (COM 2 is my free port) then CT.
> Bingo! The DX spots are flowing from CQDX-IRC internet site into CT!
> I Kept this thing running for hours and it worked flawlessly:
> not a single byte was lost.
> This, I repeat, makes it possible to get internet spots into CT,
> on a single PC, using ONLY ONE serial port and a dummy connector
> (no TNCs at all).
> 
> If you have more free serial ports or more PCs then you can use a 
> serial port cable from one PC to another (or from one port to another on
> same PC) and DXXtelnet can accomplish this as well.
> But this is a well known method (in this case also Win NT or 2000 will work)
> So with this message I wanted to put the focus on the single port method,
> which, I think, is a very original one.
> 
> You can download DXTelnet from:
> http://www.qsl.net/wd4ngb/telnet.htm
> 
> Note:
> the DXT2LOG TSR which comes with the download has a bug which prevents it
> from working properly in some cases.
> You can email me to get the fixed TSR together with the link setup tips 
> in detail.
