Kalyan,
The gray squares on the LCD simply mean that the HB doesn't have its
pcode program loaded. So it doesn't indicate a hardware failure.
With Window 2K, were you able to open "Direct to COM1" using
HyperTerminal? If no, this definitely indicates a configuration
problem with the serial port.

| Hi, Finally I found out what happened. One of the pins of the RJ-11 socket on the handyboard was disconnected from the PCB. So I soldered it back and the handyboard is working fine. Thanks for all your help. Kalyan (...) (25 years ago, 25-Nov-99, to lugnet.robotics.handyboard)
