NAME
|
||||
----
|
||||
p7os - get and change CASIO calculator's OSes using protocol 7
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
[source,bash]
|
||||
----
|
||||
p7os [-h|--help] [-v|--version] [<subcommand> [<args>]]
|
||||
----
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
p7os is a command-line utility to get and upload an OS on CASIO fx calculators,
|
||||
using its communication protocol 7.00 and OS update mode.
|
||||
|
||||
Available submenus are :
|
||||
|
||||
*prepare*::
|
||||
This subcommand must be run before *any* other subcommand. It will upload
|
||||
a P7 server that supports the commands required by them.
|
||||
*get [-o os.bin]*::
|
||||
Get OS image copy.
|
||||
|
||||
You have to *prepare* before doing any other action. Preparing means sending
|
||||
a P7 server on the calculator that will be able to execute commands required
|
||||
by other subcommands.
|
||||
|
||||
OPTIONS
|
||||
-------
|
||||
Options start with one or two dashes. Some of the options require an additional
|
||||
value next to them.
|
||||
|
||||
*-h, --help*::
|
||||
Display command/subcommand help page and quit.
|
||||
*-v, --version*::
|
||||
Display version and quit.
|
||||
*--device /dev/mydevice0*::
|
||||
The device with which to interact.
|
||||
Mostly */dev/cfx0* for USB and */dev/ttyS0* for serial connections.
|
||||
*-o OUT, --output=OUT*::
|
||||
When getting something, where to store.
|
||||

||||
