Hi guys, Here is the situation I've 89c51 microcontroller board which I want to connect with PC as well as GSM but as everybody knows it(8051) has only one UART so one solution is try using 87xx or 83xx series of controller but that means I'll have to change my programmer. So what I'm thinking is I'll use simple mux/demux for Tx/Rx of 8051. I want to know will it be o.k.? Can simple AND or OR gates can handle data rate of 9600bps?
Thank you very much in advance.
Please guys don't go for that success tag in future if somebody want to do so. I guess this method is failure anyway will let you know for sure in a day or two When I put incremental characters i.e. a,b,c,d,e,.... in transmission i got at receiver is random characters still I'll try for a day or two
