Quite a few changes were required, but all the examples now compile with FPC 3.2.2 or 3.3.1 on:

• FreeBSD (tested on 13.0-RELEASE)
• Linux (tested on Ubuntu 21.10 - Note: TLS does not work)
• macOS 10.12 and later
• Windows (tested on 10 with updated SSL libraries - see OpenSSL.pas for details)
• All insecure TLS/SSL methods have been removed (ie SSL2, SSL3, TLS v1, TLS v1.1) leaving TSL v1.2 and TLS v1.3

Instructions:

0. Compile with FPC 3.2.2 or FPC 3.3.1
1. Download a ZIP file and unzip
2. cd to the lnet-master directory
3. run make (this compiles the library and console examples - there are no Cocoa/Carbon hooks for the visual components, so they do not compile for macOS)
4. For Lazarus, add the path to lnet-master/lib to the Project Options > Paths - "Other unit files" OR
5. For FPC, use -Fu to add the path to lnet-master/lib

These units are an asynchronous, TCP/UDP communications classes. LTCP, LUDP, LTELNET, LFTP and LSMTP are example programs.

Use the makefile to compile the lib as well as examples.

All programs are compiled with Free Pascal 2.0.4 (http://www.freepascal.org)
