How do I send control characters in a script?

To send or embed control characters in strings in JScript/Javascript convert them to octal values with a prepended '\' character for example:

// send ^C, (decimal 3)

// send ^D, (decimal 4)

// send ^M, (decimal 13)

In VBScript use the Chr() function with the decimal value of the character you want to send:

' Send ^C
crt.screen.Send Chr(3)

' Send ^D
crt.screen.Send Chr(4)

' Send ^M
crt.screen.Send Chr(13)

You can use the VBScript '&' operator to concatenate strings with the Chr() function, for example:

crt.screen.Send "hello" & Chr(10) & "goodbye"
