AV Rs232 Sender

A program for sending audio and video over a one-way RS 232 connection.

This is a simple little program that uses unreal media server, live server and player to stream audio and video over a one-way RS 232 connection. the picture above is a snapshot of my screen with two instances of this program running.  There is one wire coming out of comport 4 and going into comport 5. the right instance of the program has connected to the real media server on my computer.  The left instance of the program is listening to the comport and has created a fake unreal media server at port 100. the unreal media player has connected to this fake unreal media server at port 100. the live media server is capturing my screen.

As for a how you get the RS232 data from one computer to another, a piece of wire will work, a null modem, but a project like Daniel's data transceiver will get the data from one computer to another without wires up to 115.2Kbs.

Another project of mine that is related, is my QAM soundcard modem. it uses sound to transmit data (and AV) from one computer to another up to 100Kbs.

Version 1 of the program doesn't contain any error correction for data being transmitted. Although it does have a small checksum on the packets transmitted. Version 1.1 has 15% RS redundancy forward error correction (FEC). It was written in Borland's C++ builder 6. it uses TCiaComPort 1.15,  JEDI-VCL 3.3, and ICS V6 VCL components. source code is included in the download.
