Hi Larry, It WORKS!!!! I downloaded this small "software" (it is driver installed in the system called "MixW serial port bridge") and can work RTTY using DX4WIN and MMTTY without ANY COM ports! That is great information for guys with limited serial ports in computers.
Let me to give few steps to explain how to configure drivers, DX4WIN and MMTTY (some of the information was taken from John WA9ALS's page http://www.qsl.net/wa9als/dx4win-mmtty-hardware.rtf): 1. You need Windows XP/2000 to work the combo DX4WIN/MMTTY without null-cable (I didn't try with other systms, but this info was taken from "ReadMe" file of the "MixW serial port bridge". 2. Install "MixW serial port bridge" (all information about install driver is in the ReadMe file) 3. After install open "System" from Control Panel. Next select "Hardware" tab and click "Device Manager". Find "MixW serial port bridge" under "Multi-port serial adapters". Right-click on it and choose "Properties". Select Properties tab and choose first and second emulated ports (COM101 and COM102 by default, BUT I suggest to change it to COM7 and COM8). Next close the "System" and reboot the computer. 4. Now configure DX4WIN to talk to the MMTTY. These settings are found in DX4WIN's <F>ile, <P>references, RTTY. RTTY interface: Type : regular COM Port: COM7 Baud rate: 9600 Flow control: RTS/CTS Data/Parity: 8 bits/no parity Scrollback capacity: 500 Options: X check for Dxspots _ announce DX to other window X Always in immediate mode (IMPORTANT!) X Use bell character' X Show function keys 5. MMTTY SETTINGS: Open MMTTY software and go to <O>Ptions, <S>etup TNC Emulation(T) Port definition Port: COM8 Baud: 9600 Data length: 8 bits Stop: 1 bit Parity: None Flow control: CTS TNC type: TNC241 Local echo: After Sending X Disable window (IMPORTANT - see text) _ Stay on top You should be able now to receive RTTY in DX4WIN window. If you press CTRL+T it start transmit, by using CTRL+R you switch to receive mode. Good luck and see you on RTTY Pawel, SP7PS SN7N in contests ----- Original Message ----- From: "Larry Gauthier" <[EMAIL PROTECTED]> To: <[email protected]>; "Dave" <[EMAIL PROTECTED]> Sent: Wednesday, June 12, 2002 6:21 PM Subject: Re: [Dx4win] MMTTY xmit & rcv keys > Dave (et al), > > Actually, there is very good news on the "oh no, not enough serial port" > front!! > > MixW software has developed a "serial port emulation program" that mimics > two hardware serial ports talking to each other, thus eliminating the need > for two additional serial ports to get MMTTY and DX4WIN communicating.
