Hi, I wrote 2 programs in C to read from a serial port and to write in. When I used one machine, nullmodem ( output and input) the program ran correcly, I wrote caracteres then I read them from the same port. ttyS0 for example.
they ran correctly when I used a machine with 2 serial ports ttyS0 and ttyS1, so I send from one port to another. When I tried the same programs from one machine using a crossed cable ( This is what I have to done the output of one machine is an input for the other), it failed I have to wait very long time, may be for ever !!!! I remember I didn't once or twice yesterday, but after that no connection. Is there a special configuration, activation or else ??? (on both machines I am using linuxMint, is there any relation with the distro ??) thanks a lot regards bela
