## README

Control your EPSON projector connected via USB or serial cable to your local computer or a remote machine.

Preparation
-----------

Install package `uucp` on the machine that is connected to the projector.

Installation
------------

```
npm i -g escvp21
```

Usage
-----

```
  Usage: escvp21 [options] <connect-command>

  Options:

    -h, --help                output usage information
    -V, --version             output the version number
    -m, --model <model-name>  specify projctor model. Use "auto" to query REST API based on serial number. [auto]
    -p --power <on or off>    Turn on or shutdown projector

```

Auto-Detect Projector Model
---------------------------
If you specify "auto" as model name (that's the default), the program will use a web service (see below) to lookup the projector's model name by its serial number.
Privacy notice: The unique serial number of the device in question will be sent over the network as part of a URL via https.

If you prefer to query the web service manually or the host computer where the projector is connected to does not have Internet access, you can use the following command:

```
curl "https://www.epson.co.uk/gb/en/viewcon/corporatesite/modules/warranty_details/search?ajax=true&serial=<SERNO>"
```

Examples
--------

Power up projector connected to serial port `ttyUSB0` on local machine:

```
escvp21 "cu -l /dev/ttyUSB0 -s 9600" --power on
```

Shut down projector connected to serial port `ttyUSB0` on remote machine `conema.local`:

```
escvp21 --power off "ssh -e none projectionist@cinema.local \"cu -l /dev/ttyUSB0 -s 9600\""
```

Example Output
--------------

```
$ escvp21 "ssh -e none projectionist@cinema.local \"cu -l /dev/ttyUSB0 -s 9600\"" --power on
