I am trying to run this USB Serial Monitor app on HCL ME U1 tablet (ICS 4.0.3, Kernel 3.0.8). I am connecting the tablet with a serial device using a FTDI FT232RL (USB to RS232) cable. When i connect the FTDI cable to tablet, notification asking permission to connect the device pops up and when I open device, Toast saying connected also comes up.
