If so, does anyone know WHY that is? I'm just curious. I got this USB serial adapter for something else and this is the first time I've tried to use it. I wonder if it will be a problem elsewhere also.


Broken assumptions in the original programming of the empeg tools. Real serial ports transfer characters back and forth as soon as data becomes available for transmission.

USB devices use a packet protocol, which means they prefer to gather/buffer multiple characters together before sending anything. Those characters then get sent/received as faster bundles, but with larger time gaps between bundles.

Those larger time gaps are unnatural to software that expects a Real serial port, and such software is confused by them.
