The BAFO brand unit that I have seems to work okay.  A RTTY list member also 
indicated that the Conceptronics brand adapter worked for him with Ham Radio 
Deluxe and an FT-897D.  Have you checked whether Flow Control for the 
adapter's serial port is set to "Hardware"?

For RTTY, you can use a program called EXTFSK with adapters that don't 
support 5-bit Baudot.  It's available from the MM-Hamsoft web page.

Dear George,

Thank you for the reply.

Yes, in fact I face the same problem with RTTY FSK keying with the
USB-Serial converters as you have mentioned.  I have tried updating all the
drivers and also tried a couple of converters that I have to the same

Anyhow, I guess I would just have to use a PC with physical serial ports
for this operation.  Once again, thank you for the kind reply.
