[WT-support] RTTY PTT Problem

[Peter Hansen]

To provide PTT and FSK for RTTY, I am using an FTDI USB to RS232 adapter 
connected to a Keying interface which then is connected to a Y-box 
providing the signals to the ACC port on my K3S.A second USB connection 
goes directly to the K3S for Radio Command. This setup works perfectly 
on MMTTY stand alone, and also on N1MM but not on Win-Test 4.50.0.If I 
attempt to assign PTT & FSK to COM6 on the TX Setup on the MMTTY window, 
I get the message “can’t open COM6 at 45 baud, use EXT FSK”.Using the 
EXT FSK selection as instructed does not produce any error messages, but 
the PTT and FSK functions do not work.The exact same settings on MMTTY 
stand alone and N1MM both work properly. Windows 10 computer, FTDI 
driver is up to date.
