Hardware and Performance / DEC740 Reset or Serial Install
« on: April 17, 2023, 06:36:18 pm »
I have purchased a DEC740 but unfortunately, I have messed up my network settings due to an error and now I do not know how I can connect to this device.
I have looked for a reset button, but I haven't found anything like that and my notebook just gets a self assigned IP with no way to connect to the router. (The IP it pick is 169.254.165.210 with a 0xffff0000 netmask. I have tried pinging the broadcast address, but I do not get any response.)
I now wanted to use a serial USB install and connect the device like so, but I also cannot see any device like ttyS0 or ttyUSB0.
Any help would be appreciated!
Edit 1: After I reconnected the device via USB I did find a couple of /dev/ttySX devices and /dev/ttyS0 sort of opens a connection with "sudo screen /dev/ttyS0 115200". Unfortunately, nothing happens afterwards and the screen simply remains empty.
Edit 2: ok ttyS0 is something different. I'm also using the cable the came with the device, so I assume when I connect this is should in fact by ttyUSB and not ttyX.
Edit 3: I sort of fear that the serial port has been deactivated after the "successful" configuration...
