That was my thought also. I asked about flow control, both hardware
and software, and got word from the firmware developer that the
device firmware can not be changed to support hardware flow control.
I didn't get a comment on XON/XOFF and have already asked again.
Meanwhile I wanted to also check here.

I agree. I'm trying to work toward a more advanced hardware solution.
