New Revision: 2210

Modified:
   trunk/src/jtag/amt_jtagaccel.c
Log:
Simplify and improve amt_jtagaccel_handle_parport_port_command:
- Show the port number to the user when asking for it or setting it.
- Print an error if the amt_jtagaccel_port has already been set.
- Use parse_u16 helper to ensure amt_jtagaccel_port string parses correctly.
