Can I Use powerpoint to send commands out the serial port?

I'm not a programmer, but have a decent brain. I want to send commands to a
RS232 controlled relay pack by actuating command buttons on a ppt screen. Is
there a simple code to send these commands? I have code for the relay pack
i.e...

MSComm1.Output = Chr$(254) 'enters command mode
MSComm1.Output = Chr$(9) 'turns off any relays
MSComm1.Output = Chr$(1) 'enters single relay-on mode
MSComm1.Output = Chr$(relay - 1) 'selects relay to activate

I'd also like to have the program repeat the relay off command after 15
seconds and wait for the next button activation.
