spawn pty failed: fork/exec /usr/bin/telnet: invalid argument

[gitcnd]

Using wsl1 (Ubuntu) on windows 10N, I get the following:

[cnd:~/Downloads]$ trzsz telnet 192.168.1.106
spawn pty failed: fork/exec /usr/bin/telnet: invalid argument

[cnd:~/Downloads]$ telnet 192.168.1.106

Not sure what that means, but telnet works fine by itself I know.
The telnet protocol is quite simple - should be possible to let trzsz emulate that without needing to use any external program if that helps?

The problem seems to be with trzsz code, not the program it needs to run - same error no matter what program I try to run:

[cnd:~/Downloads]$ trzsz /usr/bin/perl ~/Downloads/mcu_serial.pl -port $PORT -setdtr -setrts -norts -nodtr
spawn pty failed: fork/exec /usr/bin/perl: invalid argument

[cnd:~/Downloads]$

Which version of trzsz? Is it the Linux version or the Windows version?

[lonnywong]

trzsz in WSL

• trzsz ( Windows version ) + telnet ( Windows version )

  • The upload speed may be slow, but the download speed should be normal.
  • Check The input speed of ConPTY / ConHost is very slow. microsoft/terminal#13594

• trzsz ( Linux version ) + telnet ( Windows or Linux version )

  • You also need to install zenity in WSL.
  • Older versions of WSL may not support the zenity to open the file dialog.
  • You may be able to select files only in WSL but not in Windows.

• trzsz ( Windows version ) + telnet ( Linux version )

  • Not support.

It is recommended to use tssh.exe. I will close this issue later because there is no more information.
