When booting, the system usually makes some sort of beep or musical sound to indicate it is starting up. When this happens, to use the serial port, I believe that you need to hit a number to get it to boot from service mode. If I remember it right, the numbers were: 1 = Maintenance mode - to be able to define the console and change the bootlist 4 = Default Bootlist 5 = User-defined bootlist I can confirm that the S1 port on the newer pSeries works, and we used the IBM cable P/N 40H6328 and a DB25 null modem cable to an IBM 3151 or IBM 3153 dumb terminal at 19200 baud. IBM confirmed they upped the baud rate for the master console connection on the serial ports.the older models were all at 9600 baud.

This should also be possible to a PC running an emulator that has IBM3151 or VT100 as its options. One more silly point - the machine's power light tells you what the system is doing: Slow blink is standby, fast blink is system dump, solid is powered on. It may be necessary at times to physically unplug the unit from the power supply to get it to shutdown and reboot to see the serial connection. Finally, when you boot the system, are there any LED codes that show up? Usb Serial Controller Driver Nokia 6101 Phone. Octopus Box Cracked.
