        char ** nutscan_get_serial_ports_list(const char *ports_range);

DESCRIPTION

The nutscan_get_serial_ports_list() function returns a null terminated array of strings generated from a port range.

The 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-port device on a system.

RETURN VALUE

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.

NOTES

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