twinstar - Control the Twinstar feature of a Xorcom Astribank
SYNOPSIS
twinstar {status|jump|enable-wd|disable-wd|ports}
DESCRIPTION
twinstar is a tool to control the Twinstar (dual USB port) of a Xorcom Astribank. There is a single and mandatory argument which is the
command to run. That command operates on all the Astribanks connected to the system.
Technically all the commands are implemented using Dahdi::Xpp::Mpp which in turn uses astribank_tool. Thus using thus tool will require
root permissions or otherwise read/write permissions to the USB device.
The twinstar may be in watchdog mode, which means that it will jump to the remote host if it loses contact with the local host. This can
happen if the machine is powered down or hangs or even if the xpp drivers are unloaded. Which is why the standard twinstar scripts put the
Astribanks in twinstar mode on startup and remove it on normal shutdown.
An Astribank will only jump to the other host (either if asked explicitly or by the watchdog) only if there is a different Astribank
connected to the other port and running. Which is why all of this has no effect on systems that don't need this functionality.
The command are:
status
Shows the current status of all Astribanks. Note that it only shows Astribanks whose current active USB port is the one connected to this
computer.
Example output:
DEVICE PORT WATCHDOG POWER0 POWER1
usb:001/010 0 on yes yes
usb:001/011 0 on yes yes
For each Astribank on the system that has Twinstar support we get:
Device
The address of the device. This is the bus address, e.g. the address you see in lsusb / dahdi_hardware.
Port
The active USB port on the Astribank. This should be always '0' on the master and always 1 on the slave.
Watchdog
on if the watchdog is triggered in the Atribank or off otherwise.
Power0, Power1
Shows which ports of this Astribank are connected to a USB port of a running computer. This only shows whether or not the USB host
provides power.
ports
Shows the same 'Port' column of the status command.
jump
Command all the Astribanks to jump to the other port. This works regardless the watchdog mode is enabled or not. But requires that there is
power on the other port.
enable-wd
Enables watchdog mode.
disable-wd
Disables watchdog mode.
FILES
twinstar mostly uses astribank_tool which in turn mostly uses USB files under /dev/bus/usb .

hp-makeuri - Device URI Creation Utility
DESCRIPTION
Creates device URIs for local and network connected printers for use with CUPS.
SYNOPSIS
hp-makeuri [OPTIONS] [SERIAL NO.|USB ID|IP|DEVNODE]
SERIAL NO.|USB ID|IP|DEVNODE
USB IDs (usb only):
"xxx:yyy" where xxx is the USB bus ID and yyy is the USB device ID. The ':' and all leading zeroes must be present. (Use the
'lsusb' command to obtain this information. See Note 1.)
IPs (network only):
IPv4 address "a.b.c.d" or "hostname"
DEVNODE (parallel only):
"/dev/parportX", X=0,1,2,...
SERIAL NO. (usb and parallel only):
"serial no."
OPTIONS
To specify the port on a multi-port JetDirect:
-p<port> or --port=<port> (Valid values are 1*, 2, and 3. *default)
Show the CUPS URI only (quiet mode):
-c or --cups
Show the SANE URI only (quiet mode):
-s or --sane
Show the HP Fax URI only (quiet mode):
-f or --fax
Set the logging level:
-l<level> or --logging=<level> <level>: none, info*, error, warn, debug (*default)
Run in debug mode:
-g (same as option: -ldebug)
This help information:
-h or --help
EXAMPLES
USB: $ hp-makeuri 001:002
Network:
$ hp-makeuri 66.35.250.209
Parallel:
$ hp-makeuri /dev/parport0
USB or parallel (using serial number):
$ hp-makeuri US123456789
NOTES
1. Example using 'lsusb' to obtain USB bus ID and USB device ID (example only, the values you obtain will differ) :
$ lsusb
Bus 003 Device 011: ID 03f0:c202 Hewlett-Packard
$ hp-makeuri 003:011
(Note: You may have to run 'lsusb' from /sbin or another location. Use '$ locate lsusb' to determine this.)
