IPMItool Setup
--------------

1) Configure the SOL bitrates:

$ ipmitool -I lanplus -H <bmc-host> -U admin -P <password> -e \& shell

ipmitool> sol info
Set in progress                 : set-complete
Enabled                         : true
Force Encryption                : false
Force Authentication            : false
Privilege Level                 : USER
Character Accumulate Level (ms) : 50
Character Send Threshold        : 100
Retry Count                     : 7
Retry Interval (ms)             : 500
Volatile Bit Rate (kbps)        : 9.6
Non-Volatile Bit Rate (kbps)    : 9.6
Payload Channel                 : 1 (0x01)
Payload Port                    : 623
ipmitool> sol set non-volatile-bit-rate 115.2
ipmitool> sol set volatile-bit-rate 115.2
ipmitool> sol info
Set in progress                 : set-complete
Enabled                         : true
Force Encryption                : false
Force Authentication            : false
Privilege Level                 : USER
Character Accumulate Level (ms) : 50
Character Send Threshold        : 100
Retry Count                     : 7
Retry Interval (ms)             : 500
Volatile Bit Rate (kbps)        : 115.2
Non-Volatile Bit Rate (kbps)    : 115.2
Payload Channel                 : 1 (0x01)
Payload Port                    : 623

FreeBSD Setup
-------------

For further information, see: https://www.freebsd.org/doc/handbook/serialconsole-setup.html

1) Set up the boot block options:

# echo "-Dh -S115200" > /boot.config

2) Set the system bootstrap options:

# cat << EOF >> /boot/loader.conf
boot_multicons="YES"
boot_serial="YES"
console="comconsole,vidconsole"
comconsole_port="0x248"
hint.uart.0.flags="0x00"
hint.uart.2.flags="0x10"
EOF

3) (OPTIONAL) Enable a login prompt on the serial console by editing the ttyu2 line in /etc/ttys to read:

ttyu2   "/usr/libexec/getty std.115200" vt100   on  secure

4) After rebooting, the check the dmesg(8) output:

# dmesg | grep uart
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 on acpi0
uart2: <16550 or compatible> port 0x248-0x24f irq 3 flags 0x10 on acpi0
uart2: console (115200,n,8,1)

5) Start a SOL session

$ ipmitool -I lanplus -H <bmc-host> -U admin -P <password> -e \& sol activate
[SOL Session operational.  Use &? for help]

FreeBSD/amd64 (unas) (ttyu2)
