#113177 - Not RS232 Responding to: ???'s previous message |
As Kalpak Dabir has already said, RS232 is not a bus - so you cannot do this with strictly RS232 - in particular, you won't be able to include the PC on any "bodge" that you might devise.
http://www.8052.com/forum/read.phtml?id=113174 See also: http://www.8052.com/forum/read.phtml?id=110865 For a standard approach, RS485 would be the way to go. If you do, be sure to follow Erik Malund's recommendation: http://www.8052.com/forum/read.phtml?id=111584 Also, go to the 'Links' page and search for "Best Serial Comm Appnote site"... And also search this forume for the very many previous discussions of RS485. |
