[Dx4win] TXing with MMTTY and PSK31?

[Eric Rosenberg]

I can receive in both modes, but can only transmit via the the function
keys (i.e., canned messages).

For some reason, I am unable to send from the KB. I type in the lower
window, press <enter> on the KB and nothing happens.

I'm using a MicroHam MK2 as the interface.

Thoughts?
