PSK and FT8 with PC Client

[w2hdi]

I am using PC Client with the "B" connector and Ham Radio Deluxe to operate my remote IC7100.  Receiving PSK is great, but I can't figure out how to key the transmitter.  What is the role of the "red" button?
I wonder if anyone has figured out how to operate the new FT8 mode using PC Client?
Thanks

Arnie,

The red button is PTT,  only really useful for SSB.

I would use the VOX function of your rig and see if that works. It usually switches immediately in
data or CW mode.
