virtual terminal to be opened on the

HMC. Open a virtual terminal.

2. If a virtual terminal is open, the user

off of the screen. If this is the case,

enter a CTRL-Q key sequence to

resume scrolling.

3. Check the serial connection between

the HMC and the managed system.

4. Reboot the HMC.

5. There may be a hardware problem with

codes that indicate a problem with the

serial ports on the service processor.

The service processor is in the primary

I/O book at the U1.18-P1-H2 location.

Take the appropriate actions based on

the error codes that are found.
