NAME¶

plcotst - PLC One-Time Self-Test Manager

SYNOPSIS¶

plcotst [options] [device] [device] [...]

DESCRIPTION¶

Manage the PLC One-Time Self-Test feature on Atheros powerline devices. Normally, selftest is performed once, on startup at the factory, but it can also be configured and run again using this utility. Selftest results are stored by the firmware and can be read using this utility, as well. The selftest is configured when configuration options are specified on the command line; otherwise, selftest results are read or cleared.

This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for an overview and installation instructions.

OPTIONS¶

-c version

Configuration version number. Permitted values are 0 through 255. The default is 0. This option applies to both selftest configuration and selftest results.

-C

Clear stored selftest results. This option clears stored selftest results. This option implies selftest results and supercedes options -d, -f, -m, -r and -R, if present on the command line.

-d seconds

Delay selftest after reboot. Permitted delay times are 0 through UINT_MAX seconds. The default is 0 seconds. This option implies selftest configuration and supercedes option -C, if present on the command line.

-e

Redirects stderr messages to stdout. By convention status and error messages are printed on stderr while primary program output is printed on stdout. This option prints all output on stdout in cases where this is desired.

-f count

Run the flash memory selftest count times. Valid values are 0 through UINT_MAX. The default is 0 which effectively suppresses the test. This option implies selftest configuration and supercedes option -C, if present on the command line.

-m count

Run the memory selftest count times. Valid values are 0 through UINT_MAX. The default is 0 which suppresses effectively the test. This option implies selftest configuration and supercedes option -C, if present on the command line.

-q

Suppresses status messages on stderr.

-r flag

Run selftest after reboot. Permitted values are 0 through 255. Expected values are 0 for false and 1 for true. The default is 1. If the memory test count and flash test count are both 0 no testing will occur when the time comes. This option implies selftest configuration and supercedes option -C, if present on the command line.

-R flag

Reset device after selftest. Permitted values are 0 through 255. Expected values are 0 for false and 1 for true. The default is 0. This option applies to selftest configuration only and supercedes option -C, if present on the command line.

-t timeout

Read timeout in milliseconds. Values range from 0 through UINT_MAX. This is the maximum time allowed for a response. The default is shown in brackets on the program menu.

-v

Print additional information on stdout. In particular, this option dumps incoming and outgoing packets which can be saved as text files for reference.

-?,--help

Print program help summary on stdout. This option takes precedence over other options on the command line.

-!,--version

Print program version information on stdout. This option takes precedence over other options on the command line. Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version of the Linux Toolkit you are using.

ARGUMENTS¶

device

The Ethernet hardware address of some powerline device. More than one address may be specified on the command line. If more than one address is specified then operations are performed on each device in turn. The default address is local. as explained in the DEVICES section.

EXAMPLES¶

The following example prints stored test results for the local device on stdout because no options are specified on the command line.

# plcotst

The next example prints stored test results for remote device 00:B0:52:BA:BE:DE and clears them afterwards.

# plcotst -C

The next example configures the PLC selftest to wait 5 seconds before execution because option -d is present. It also configures the selftest to reset the device after execution because option -R is present

# plcotst -d 5 -R
