To set up a serial console to, for instance, capture kernel panic information ...
Set up system to do the monitoring
- Start "minicom -s -o"
- Under "Serial Port Setup:"
- Set Serial Device (A) = /dev/ttyS0
- Set BPS/Par/Bits (E) = 115200 8N1
- Set Hardware Flow Control (F) = Yes
- Set Software Flow Control (G) = No
- Under "Modem and dialing" clear:
- Init String (A)
- Reset String (B)
- Hang-up string (K)
- Save profile with a name like "ttyS0"
- Under "Serial Port Setup:"
Set up system to be monitored
- Edit /etc/grub.conf and add kernel boot parameters "console=tty0 console=ttyS0,115200"
Start monitoring
- Get a null modem serial cable and connect the systems to each other. (I assume the use of COM1/ttyS0 here but that isn't required)
- Start minicom on the monitoring system with "minicom ttyS0" (using the name of the minicom profile you saved above)
- Reboot monitored system, the console should be displayed in minicom on the monitoring system
