# nutscan\_scan\_eaton\_serial(3)

Scan serial ports for Eaton devices (XCP, SHUT and Q1).

## NAME

nutscan\_scan\_eaton\_serial - Scan serial ports for Eaton devices (XCP, SHUT and Q1).

## SYNOPSIS

```
        #include <nut-scan.h>
        nutscan_device_t * nutscan_scan_eaton_serial(const char* ports_list);
```

## DESCRIPTION

The **nutscan\_scan\_eaton\_serial()** function tries to detect NUT devices which are compatible with Eaton’s serial device protocols (SHUT, XCP and Q1 (aka blazer or megatec)).

*ports\_list* is a NULL-terminated array of pointers to strings containing serial device name (/dev/ttyS0, COM1, /dev/ttya...)

You MUST call [**nutscan\_init**(3)](/nutscan_init/3.md) before using this function.

## RETURN VALUE

The **nutscan\_scan\_eaton\_serial()** function returns a pointer to a nutscan\_device\_t structure containing all found devices or NULL if an error occurs or no device is found.
