unique lost root password
Ok,
I lost the root password. I can get to the MP via ethernet. But I cant connect to the serial port on the back of the machine via terra term or similiar terminal application. Therfore I cant send a break to get to the solaris = of OK prompt in HP(what do you call this in HPUX anyways?).
I looked at the other links and all of them assume you have console access, which i dont. I tried putting the cd in the drive but i cant get it to boot off the cdrom. Any ideas out there? This is an hp-1440. What kind of cable do i need to connect to the serial console port?

I've forgotten root password on one of Solaris machines, i searched in forumes to find a similar case but there's no proceudre here to reinintialize root password, cause most of related commands & even single user mode needs root password that i don't have.
Any solution would be helpful.

dc(4) Kernel Interfaces Manual dc(4)
Name
dc - serial line/mouse/keyboard
Syntax
device dc0 at ibus? vector dcintr
Description
The serial line controller provides four ports, with modem control on two of the ports. The DECstation 3100 and DECstation 2100 only pro-
vide partial modem control. The DECstation 5000 provides full modem control. The ports are used as follows:
Port Usage
0 Graphics device keyboard at 4800 BPS
1 Mouse or tablet at 4800 BPS
2 Communications port 1 (w/modem control)/local terminal
3 Communications port 2 (w/modem control)/local terminal
Each communication port from the serial line controller behaves as described in and can be set to run at any of 16 speeds. For the encod-
ing, see
When a graphics device is not being used as the system console, communications port 2 becomes the system console. In this configuration,
the port can only be used at 9600 BPS and no modem control is supported.
The serial line driver operates in interrupt-per-character mode (all pending characters are flushed from the silo on each interrupt).
Restrictions
Speed must be set to 9600 BPS on the console port and 4800 BPS on ports used by graphics devices. The serial line driver enforces this
restriction; that is, changing speeds with the command may not always work on these ports.

local terminal
