Currently, we limit the total ports number to 256. It is quite common for PBX or SMS gateway to be equipped with a lot of modems. In now days, a modem could have 2-4 control ports or even more, what only accelerates the ports exhausing rate. To avoid facing the port number limitation issue reports, increase the limit up the maximum number of minors (i.e. up to 1 << MINORBITS).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
