nutscan_get_serial_ports_list - Get a port list name from a range of port.

#include <nut-scan.h>

char ** nutscan_get_serial_ports_list(const char *ports_range);

The nutscan_get_serial_ports_list() function returns a null terminated array of strings generated from a port range. ports_range may be one of:

•a single character from 0 to 9 or a to z representing a serial communication port depending on the operating system. For instance "0" is converted to /dev/ttyS0 and /dev/ttyUSB0 on Linux; "1" is converted to COM1 on Windows; "c" is converted to /dev/ttyc on Solaris...

•a range of character in the form "X-Y". For instance "0-1" will be converted to /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0 and /dev/ttyUSB1 on Linux; "1-3" will be converted to COM1, COM2 and COM3 on Windows; "a-c" will be converted to /dev/ttya, /dev/ttyb and /dev/ttyc on Solaris.

•a single port name (/dev/ttyS5, COM4...).

•a list of port names separated with commas: "/dev/ttyS0,/dev/ttyS2,/dev/ttyS4" or "COM1,COM3"...

The returned array can be used in a call to nutscan_scan_eaton_serial to get the serial device on a system.

The nutscan_get_serial_ports_list() function returns NULL if an error occurred (invalid port range) or a pointer to a null terminated array of strings on success.

Technically, the function is currently defined in nutscan-serial.h file.
