#99981 - do you set SCON as a byte or bitwise ?
Responding to: ???'s previous message
do you set SCON as a byte or bitwise ?

set SCON as a byte, it is not unusual that during power up the RxD get toggled. In such cases, a bitwise set of the SCIN values does not remove the RI.

so, instead of
sbit SM1
sbit REN

make it SCON = M_SM1 + M_REN
