 		 #163590 - what registers?
Responding to: ???'s previous message
No, unless you switch the registers for sending and receiving, which only works of course, if the receiving line is quiet when sending. Otherwise data gets lost.
what registers?

since I have never tried this, I can not say with full authority that it will work in full duplex (although I think it will send/recieve are separate after all) but it will work in half duplex, else there would have been no reson for separate T2CON bits.

Is possible? AT89S52 with dual serial baud rate            01/01/70 00:00      
   yes...            01/01/70 00:00
