Symptoms Possible
cause(s)
Solution
Serial port(s) do not work.
Port is disabled in the
Setup screen.
Interrupt conflicts.
Port hardware failure.
Enter the Setup screen. Use cursor
arrows to move to the appropriate
field and toggle the entry to enable
the port.
Another module may be using the

Problem
:
The DOS operating system cannot find the Command line interpreter.
Solution(s)
: Either
