Cygwin Windows --> Accessing serial port.

Don't hold the power on button.  You should just press and release the power button to start the bootloader.



I was able to access the serial port.

I ran the following command

./osmocon -p /dev/ttyS5 -m c123xor  ../../target/firmware/board/compal_e88/hello_world.compalram.bin in cygwin

I then held the power on button of the phone for some time. I got some output on the cygwin console.It isn't the expected output as per the wiki.

 After disconnecting, I tried to run the same command and nothing is happening.

Can some one please suggest me what steps I need to take to solve the problem.

I am using  Motorola C115 phone.

At least on my Cygwin installation under Windows XP the serial port
is accessible as "/dev/ttySx" (x is "0" for COM1, "1" for COM2 and
so on). All the USB to serial converters I am aware of are virtual
COM ports on Windows which means that they are accessible the same
way, e.g. if the virtual COM port is "COM7" it can be be accessed
as "/dev/ttyS6",
