Re: Virtual device in Windows 10




I downloaded an updated version of the Cygwin tools and tried again....

C:\cygwin64\bin>socat -d -d pty,link=/dev/ttyV0,waitslave tcp:
192.168.0.11:8023
2019/01/01 01:14:27 socat[10780] N PTY is /dev/pty0

2019/01/01 01:14:28 socat[10780] N exiting with status 0

Can you tell why the PTY is closing ?
