Hi. I need you help.
In regedit in key
HKEY_CLASSES_ROOT\telnet\shell\open\command

In my regedit i have "C:\Program Files\NetSarang\Xshell 4\Xshell.exe" -newwin "%1".
I need insert "newtab". i wanna centralize all conections in open one program.
I try... but wrong conections.
"C:\Program Files\NetSarang\Xshell 4\Xshell.exe" -newtab "%1"
or
"C:\Program Files\NetSarang\Xshell 4\Xshell.exe" /T "%1".

Best Regards.
Thanks.

Program Ver. : Xshell 4

You can just use:

"C:\Program Files\NetSarang\Xshell 4\Xshell.exe" -url "%1"

-newtab is for naming the new tab.
