Peter Henr #1 / 3	sending CTRL+Z to the COM port!!? I'm writing a program which required to send CTRL+Z to the COM port... it goes like this: MSComm1.Output = "AT+CMGS=1" MSComm1.Output = "message blah blah" + [HERE] at the [HERE] I should be sending CTRL+Z but I don't know how, could anyone let me know? Is it Chr(something) ? Thanks! Peter

Thomas Lu #3 / 3	sending CTRL+Z to the COM port!!? There is no such thing as a Ctrl+Z charcter however in the old terminal days, you used the control key with a alpha character to send control codes ASCII 1 to ASCII 26 out the serial port. The character that you want to send is the ASCII 26 character, i.e. Chr$(26) The Z character is the 26th character of the alphabet so a Ctrl+Z is really an ASCII 26. Ctrl+M would be an ASCII 13 because the letter M is the 13th character in the alphabet.
