Thanks for the suggestions. I'm trying with socat, but it doesn't seem
to be working. I ran the following commands on the two ends:
OpenBSD: socat /dev/cuaU0,raw,echo=0 tcp-listen:8888,reuseaddr
Linux : socat PTY,raw,echo=0,link=/dev/ttyVUSB0 tcp:100.64.1.2:8888
When I try to flash the program, I get the following error.
Serial port /dev/ttyVUSB0
Connecting...
Failed to get PID of a device on /dev/pts/3, using standard reset sequence.
