hello .. my micro for an specific application has two uarts on chip. how do you configure the monitor-51 for the second uart2,which has different address mapping in sfr registers and also my micro works at 3.58 MHz freq . the address mapping of uart2 is as follows... scon - 0xc0 sbuf - 0xc1 sbaudL - 0xc2 sbaudH - 0xc3. suppose, i need to configure uart2 say for 9600 bps. what all things need to be changed in install.a51 file ..?? which command should be used to generate mon51.hex file ..?? example : install 1..2(serial type) 7f 0 I am not gettting which serial type to use, with the install command ?? thanks .. pruthvi
