I'm interested if somebody has any ideea how to write a program that is able to sniff the data passing through a serial port the same way tcpdump is able to show the data passing through the ethernet cable, i.e. without disturbing the application that sends/receives the data. I've seen few programs that basically work as tunnels opening a pseudo-console where the application connects and writing on the other side to the serial device. This approach is not very useful because I want to be able to start/stop my sniffer without interupting the communication and also the application can control different settings of the serial port which probably will not be forwarded by the tunnel. Thanks, mache
