Cabling and adapters to communicate to service processor serial port from Windows PC with USB port.
Hello,
I have an unloaded T5140 machine and want to access the ILOM for the first time and subsequently the network port after that., and then load Solaris 10 the final January 2011 build.
The first part is what confuses me -the cabling.
I am coming from a Windows machine (w/appropriate terminal emulation) via a USB port. The machine came with no cables or adapters -I have located the right Sun DB9 to RJ45 crossover adapter which is usually shipped with the machine. I need to connect to that from the PC.
The USB to DB9 cables I am seeing for sale are USB to RS232 serial. I need some sort of DB9 receptacle to plug into the Sun crossover adapter the other side which connects to the serial management port on the T5140. I think I need USB straight "uncrossed over" wire to the Sun adapter somehow and am confused because these USB to RS 232 cables advertised are already "crossed over" which would result in inverting the signal twice. Sorry for my ignorance and confusion
, but I want to get this right.. Put simply-
What should I use to connect from my USB port to the Sun crossover adapter?
Thank you in advance.
joe

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.
