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 01:14:27 socat[10780] N opening connection to AF=2 192.168.0.11:8023 2019/01/01 01:14:28 socat[10780] N successfully connected from local address AF=2 192.168.0.18:55426 2019/01/01 01:14:28 socat[10780] N starting data transfer loop with FDs [5,5] and [6,6] 2019/01/01 01:14:28 socat[10780] N read(5, 0x600056500, 8192): Input/output error (probably PTY closed) 2019/01/01 01:14:28 socat[10780] N socket 1 (fd 5) is at EOF 2019/01/01 01:14:28 socat[10780] N socket 1 (fd 5) is at EOF 2019/01/01 01:14:28 socat[10780] N socket 2 (fd 6) is at EOF 2019/01/01 01:14:28 socat[10780] N exiting with status 0
Can you tell why the PTY is closing ? Regards, Gary G.
