What type of computer and console do you have? If it is a workstation with Xwindows, turning off the monitor should have no effect at all. If it is a server and the console is an HP terminal such as the 700/96 or similar, there should be no problems. The HP terminal has hundreds of configuration options so in case someone has been 'playing' with the terminal settings, you should put the terminal back to normal:
1. Turn off the HP terminal
2. Hold down the D key (letter D on the keyboard) and turn on power
3. Keep holding the key until you see the reset message.
4. Check the baud rate, the emulation mode (HP), the pacing (XON/XOFF), turn off ENQ/ACK, and set the straps: G and H to inhibit the HP3000 handshake requirements.
If your console is a PC or a non-HP dumb terminal, the terminal is probably locking up during turn-on due to handshaking. Make sure that XON/XOFF is selected and if possible, select XON=any.
