hi

1. can we communicate between a window machine and rtos machine using serial port...
2. can we set reset RTS and CTS lines ...is there any special care to be taken with regards to network byte order or something....

3. how can we check the status of RTS using linux programming.....

YES,

2. can we set reset RTS and CTS lines ...is there any special care to be taken with regards to network byte order or something....

We can reset RTS and CTS by using
outb (0x02, PORT+4); // PORT may be 0x3F8/0x2F8
outb(0x10, PORT+6); this is reference to little endian mode

Any how untill you need handshaking there is no reqirement of this. Even in hardware use RX, TX and Gnd.. 3 pins only, serial cable should be cross connected (check this once again)

3. how can we check the status of RTS using linux programming.....

to check the satus read this PORT+4, PORT+6


hope this helps ...
