My script is not executing after Socat opens a serial connection to a cisco switch. How to fix this?

      #!/usr/bin/expect -f
      socat.exe `tty`,raw,echo=0 /dev/ttyS4,raw,echo=0,setsid,sane
      after 10
      send "\r"
      expect "switch1>"
      send "enable\r"
      expect "*assword:"
      send "PASSWORD\r"
      expect "*#"
      send "sh ip int brief\r"

CodePudding user response：

Backticks are a shell thing, not Tcl/expect. The equivalent in expect would be

spawn socat.exe [exec tty],raw,echo=0 /dev/ttyS4,raw,echo=0,setsid,sane
