I am trying to control my modem connected to the serial port by sending AT command with LabView. So that the modem will send text message to the other modem in designated events.
Inputting the following statement in "HyperTerminal" of Windows 2000, I can send message to the other modem. AT+CMGS="8040001"<CR><LF>Hello!<ctrl-Z> In the statement above, "8040001" is the phone number of the modem to be connected to. <CR> is carriage return, <LF> is the line feed, "Hello!" is the message content, <Ctrl-Z> is the keystroke to send the statement. To input the AT command above with Labview, i need to construct a string of the command above and input it into the "Serial Write" vi (Pls correct me, if I am wrong). But what is the equivalent of <Ctrl-Z>, the keystroke in hyperterminal to send the last command, in LabView. I.e. how do I make my LabView to "Press" <Ctrl-Z> programmatically. Pls help Roger
