Strange error

Hi When I try to load any program from firmware/board/compal_e88/ to my C118 phone, I receive error below: ioctl(TIOCGSERIAL): Invalid argument I upload program successfully and I receive DOWNLOAD ACK from phone properly, but then I receive this strange ioctl error. I'm running Ubuntu 9 and I tried to load compal_dsp_dump.compalram.bin layer1.compalram.bin loader.compalram.bin Result is same for all of the above. Please advice. Thanks
