Hello, Rams! Sure it is possible. But what are RS232 commands? Are these commands send through rs232? Microchip has many AN's about serial communication, just take a look at http://www.microchip.com/10/Appnote/index.htm SR> Is it possible to send RS232 commands using a pic to another pic without SR> using a PC and get some data? SR> If any one has related app notes pls send it across for reference Best regards, Oleg mailto: remove_this_word.sergin@fcita.dn.ua
