Hi, I tried this again, and it is only partly working. First, I: 1) Set in the BIOS: SET CONFIG EMS CONSOLE 1 (=> DISABLED) SET CONFIG EMBEDDED SERIAL PORT 2 (=> COM2) SET CONFIG VIRTUAL SERIAL PORT 1 (=> COM1) SET CONFIG BIOS SERIAL CONSOLE BAUD RATE 9600 SET CONFIG BIOS SERIAL CONSOLE PORT 3 (=> COM2) 2) Enable ttyd0 in /etc/ttys with vt100 emulation: ttyd0 "/usr/libexec/getty std.9600" vt100 on secure 3) Set the boot loader to use serial port: echo '-h' >/boot.config Then I get the BIOS, the bootloader and the kernel output. However, once booted, the system then only sees one serial port: root@cache12:/etc# grep ^sio /var/run/dmesg.boot sio0: configured irq 3 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: configured irq 3 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: <Standard PC COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on acpi0 sio0: type 16550A, console sio0: [FILTER] It does not give me a login prompt, instead it gives that on the physical serial port! I want everything to be on the vsp. Enabling the EMS console on either port did not help. You can download acpidump -dt output from http://anders.fupp.net/test/acpidump-vsp-com1.txt. Any clues?
