[clug] USB to RS232 DB9 Adapter

[Bryan Kilgallin]

My ancient DOS palmtop is very unreliable. So I wanted to port its 
applications to my PC.

Thus I bought this converter.

{Connect a variety of legacy RS-232 devices to your modern computer with 
this simple adaptor.



• USB 1.1 compliant

• Speed: Over 250kbps

The miniature Driver CD contains a Linux directory.
Within which are:
	* "log" directory; and
	* "ld_pl2303_v0728.rar" file.
The "log" directory contains the files:
	* "lenovo_reaper.db7"; and
	* "reaper.log".

I opened "ld_pl2303_v0728.rar" with Archive Manager". Copying the 
results into a folder on my PC's Desktop.
That folder contained these directories:
	* "Redhat8";
	* "Redhat9"; and
	* "Redhat73".
"Redhat8" contains these files:
	* "Makefile";
	* "pl2303.c"; and
	* "ReadMe.txt".
"ReadMe.txt" began thus.
{To install driver -
         make inst (The Makefile will check the module and compile and 
link it automatically. It will also remove
                    the loaded USB-Serial driver)}

Next I opened a Terminal window. Changing the working directory to 
"Redhat8". Then I entered "make inst". With this output to screen.

}

My PC is running Ubuntu 18.04.2 LTS.

Please walk me through a fix.
