So how about using an ethernet to serial adapter to gain access to the switch serial management port remotely? See attached.
Obviously I would recommend that you fully test the solution locally on an identical switch if you have one, before shipping to the remote site for somebody to simply plug in.
I've successfully used such devices to access serial ports of remote RAID controllers using nothing more than an IP address from PuTTy.
Just an idea. There are, of course, a variety of ethernet to serial adapters out there. Just search for them.
I have a serial modem connected to a usb port using an adapter cable. The system is a HP DL360. RedHat ES3.0
I am using the device /dev/ttyUSB0
When I issue the command "mgetty ttyUSB0" I get the following output in the log file.
How do I get the system to see the modem.

According to sco6 usb supplement, once you install it, you can install a bafo industries (BF-810) in the computer. I have done all that and followed the intructions completely and it shows up using usbprobe and l /dev/usb_ser*
Problem is that when I go to mkdev serial, it is not there.

PCWEASEL(4) BSD Kernel Interfaces Manual PCWEASEL(4)NAME
pcweasel -- Support for the PC-Weasel serial console board
SYNOPSIS
pseudo-device pcweasel
weasel* at pci? dev ? function ?
Note that the appropriate display device must also be enabled. See pcdisplay(4) for more information.
DESCRIPTION
The PC-Weasel is a serial console board for use primarily on Intel-based PC-class systems. It addresses a problem that nearly everyone who
has deployed a PC-class server has experienced: the total lack of remote management capability on PC-class hardware.
In addition to serial console support, the PC-Weasel provides the ability to remotely reset the system (by means of a hardware reset signal),
and provides a watchdog timer function.
The PC-Weasel works by emulating the original IBM Monochrome Display Adapter (MDA). Writes to the display's character cells are translated
into ANSI terminal sequences which are then sent out the PC-Weasel's serial port. Incoming characters are translated into PC keyboard scan
codes and then fed (by means of a cable) into the system's keyboard controller. The system believes it is using a display console. This is
particularly important in the event that one needs access to BIOS configuration menus.
The PC-Weasel also includes a ST16550 serial port, which may be configured as any one of the system's serial ports. Typical usage is to con-
figure the port as com0 at ISA I/O address 0x3f8. When the PC-Weasel detects activity on the ST16550, the serial port is automatically con-
nected to the ST16550 so that the serial port may be used as normal. When the PC-Weasel detects activity on the internal UART used for MDA
emulation, the serial port is automatically reconnected to the emulation UART. This allows the boot program and kernel to be configured to
use the serial port directly (which is more efficient than using the MDA emulation mode), yet allows the MDA emulation to be reestablished as
soon as the kernel loses control of the system.
The pcweasel driver provides support for the additional features present on the PC-Weasel. At the moment, this includes support for the
watchdog timer function. Use of the pcweasel driver is not required in order for the system to function with a PC-Weasel installed so long
as only the MDA emulation and ST16550 serial port functionality is required.

The pcweasel driver first appeared in NetBSD 1.5.1.
