Your "Recv Pace" is also know as "Flow Control" and a method for 
stopping/starting data flow. The DTR flow control is a hardware signal 
that must be on for any data to flow. DEC never used DTR for flow 
control, but it did use Xon/Xoff. The values of 64/128 are thresholds of 
data in your terminal buffer when the flow control stops and starts. No 
flow control, or "None", will only cause some data loss when the volume 
of data overflows your terminal buffer. This happens more often at 
faster baud rates, when your display is slow like with "Smooth 
Scrolling", or stopped with a "Hold Screen" function. You should disable 
all flow control using "None" at first until you get it working. Then 
later you can adjust the flow control setting to prevent data loss as 
needed.
