There is no flow control for any serial port available on the TS-7390.
I left a few messages on this forum a couple of months ago about my
difficulties finding a USB serial adapter where flow control worked
properly.
The only port with flow control is the port used for the console and TS
didn't connect the flow control pins on the micro. I wish they had used
the second port for the console and wired those pins so there would have
been at least one port with flow control.
In the final product I guess I'll need to use some DIO lines for flow
control as I don't want to use a USB serial adapter in the product.
