No, it only does serial control, and you need that for RTTY. To that 
you must add input and output connections to/from your computer 
sound card and the radio out/in.  See 

http://audiosystemsgroup.com/HamInterfacing.pdf

and http://audiosystemsgroup.com/RFI-Ham.pdf

for detailed advice that is very inexpensive. All you need to buy 
are a few connectors and/or cables. 

If you have extra money laying around, you can buy a dedicated ham 
interface box.
