Hi to all!
I recently got TruTTY in order to update my digital software on a new computer running Windows 7. I got the software working fine. However, I have RTTY running on AFSK because I have not found a setup that will work on FSK. MMTTY from Makoto Mori is working well using the FSK.dll, which is what I have used for years in Windows XP. In the case of TruTTY in FSK mode, i can get the radio to key and generate either a mark and space tone, but not the diddle, even though there is a TxD block in the setup. My guess is that there is one setup where the DTR/RTS pins (1 and 2) blocks must be checked for it to work.
Thanks for any help you may be able to provide.

I don't know anything about TruTTY but this excerpt from the RBII manual might give you a clue ...
Step 2b: Configure the PC and Radio for RTTY FSK OperationPresently, to our knowledge the only RTTY software that works with the
RIGblaster Plus II or any USB-to-serial interface is MMTTY, and that
only by using the author’s EXTFSK extension.
The reason is that USB to
serial interfaces will not go down to 45 baud
Follow the MMTTY Help files for setting up the program using the
EXTFSK extension to use the correct COM port with PTT on RTS and
FSK keying on DTR.
Once configured, transmit with MMTTY and watch the PTT and CW
LEDs. The PTT LED should be on steadily and the CW LED should
flicker with the RTTY. Confirm with the radio’s monitor that the FSK
output sounds like RTTY.
You will also have to make sure that your mark and space tones a re
correct by setting the radio and/or the software so that transmit and
receive mark and space tones are correct. The only easy way to do
this is on the air.
So it looks like if you are not running MMTTY and EXTFSK extension, it might not work???
Just an observation.
