Re your post#1, in Solaris 11 the root user (superuser) is a 'role' by default and cannot be logged into directly, only su'd to.
This is, of course, for security reasons. However, if you so choose, you can revert user 'root' to a standard user account by issuing:#
Code:
# rolemod -K type=normal root
having previously su'd to gain superuser rights. After that, subject to setting/knowing the root user password you can log directly in as root giving you immediate superuser rights without the need to su.
Another option would be to start your system in single user which brings it up in superuser but without multiuser services such as networking. However, you could soon script yourself something to start the services you require, mount filesystems, and other things whilst you are still in single user. It just depends on whether one single user (from the console) will serve your purpose. Perhaps provide us all with more information so that we can be more specific.
Code:
kevin@OptiPlex-2:~$ rolemod -K type=normal root
rolemod: command not found
kevin@OptiPlex-2:~$
"start your system in single user" This sounds great, how do you do that? Are you using Solaris?

umcs
UMCS(4) BSD Kernel Interfaces Manual UMCS(4)NAME
umcs -- USB support for serial adapters based on the MCS7820 and MCS7840 chips
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device usb
device ucom
device umcs
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
umcs_load="YES"
DESCRIPTION
The umcs driver provides support for various multiport serial adapters based on the MosCom MCS7820 and MCS7840 chips. They are 2- or 4-port
adapters with full-featured 16550-compatible UARTs and very flexible baud generators. Also, these chips support RS422/RS485 and IrDA opera-
tions.
The device is accessed through the ucom(4) driver which makes it behave like a tty(4).
Different ports on device are presented as sub-units, like /dev/ttyU0.1 and /dev/ttyU0.2.
HARDWARE
The umcs driver was tested on the following adapters:
o ST Lab U-360 two-port serial USB adapter
o ST Lab U-400 four-port serial USB adapter
SEE ALSO tty(4), ucom(4), usb(4)HISTORY
The umcs driver appeared in ports since December of 2010.
AUTHORS
The umcs driver was written by Lev Serebryakov <lev@FreeBSD.org>.
BUGS
This driver doesn't support access to any fine tunes of chip, like RS522/RS485 mode, non-standard baudrates, etc.
