How can I pipe the output of the serial port to a file in Windows?

In Linux the command would be:

cat /dev/ttyS0 > /opt/logs/Serial.log

I guess:

copy com1: somefile.log

There is also con: and nul: special device as I remember. But that was true for times when DOS was more popular. Probably now you have to create some strange file/folder with extension where in curly brakets is placed some scary long sequence of numbers and letters :)

I find more usefull this one:

type com1: >> data.log

The main advantages versus a copy is that you can append data to an existing file and you can open the file with another application (notepad) to see the contents.
