How to send ASCII control characters

Posted by doublea1535 (doublea1535), 19 August 2006

I am having a bit of a problem trying to send ASCII control characters like spacebar. One thing I am curious about is what code type do I use? decimal?

I am referencing this list:

http://www.i-logic.com/serial/ascii.htm

I thought it was decimal so I am trying:

send \032
send \32

This is not have the desired effect however.

send \x20
will send a space character; replace the 20 with ANY other hex code that you need for any one of the 256 ASCII characters.

For a space, you can also write
send " "
(there's a space typed between the two double quotes)
