(also, I suspect that the network-attached ICAT is of a no help if your driver hanged or trapped the machine, so I see no alternative to a COM port. And it's cheap to buy a PCI, or PCI-e COM port board, if not integrated. I have a COM port even on my ThinkPad's docking station. |

Also, I can use any laptop under any OS, as I have an USB2Serial adapter (Prolific pl2303-compatible), and I can attach a null-modem cable for it. I cannot type the kernel debugger commands, though, as I use a 9-to-25 pin null-modem cable, then 25-to-9 converter, and then an USB2Serial adapter, so TX signal is lost somewhere, and I cannot type commands. But I can receive COM port output, and this is sufficient. If I attach to a physical COM port, I can both TX and RX working, so the kernel debugger is working) |
