[Dx4win] MMTTY xmit & rcv keys

[Pawel, SP7PS]

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
