You cand find the name of the devices in the ecos.ecc file of your build tree. You can imagine some test case, something like sending an out of the range for tty char over the serial port and trying to read it from your PC. If you have a tty driver you will get nothing on the serial of the PC, else you will get the char. First of all, be sure that the serial on your Integrator works.
