Save as name.vbs

set my = WScript.CreateObject("WScript.Shell")
my.run("C:\Windows\System32\cmd.exe")
WScript.Sleep 3000
my.SendKeys("telnet 192.168.0.1~")
WScript.Sleep 5000
my.SendKeys("admin~")
WScript.Sleep 3000
my.SendKeys("admin~")
WScript.Sleep 3000
my.SendKeys("ppp config 0.8.35 down~")
WScript.Sleep 5000
my.SendKeys("ppp config 0.8.35 up~")
WScript.Sleep 5000
my.SendKeys("q~")

Unfortunately, I don't know Perl, maybe there are simpler options. It is necessary that the script be executed automatically through the task scheduler. Or maybe there is a program that allows you to automate the execution of telnet commands.
