I am new to this Arduino thing.
But I am a retired EE with over 40 years design experiance. I have been programming the Atmel ATmeaga devices in assembly language for several years.
Today while looking it the Arduino UNO I noticed the USB/RS-232 bridge chip. Is the code for this chip available somewhere? I would like to find both the source and hex files?

You mean the 16U2 chip that is programmed for USB/TTL Serial? (not RS232, which is +/- 10V or higher signals)
I know it's posted, not sure if part of the IDE download (so already on your computer) or if up at GITHUB somewhere.
Yes it is the 16U chip I am interested in. I would like to find both the source and hex files if possible.
I have been using the FTDI DLP module for my projects and this looks like a cheaper option.
I use FTDI modules to avoid the extra programming. Plus the modules don't have impossibly tins legs to solder.
Oh, and Welcome to the forum.
I have all the code written for the FTDI both for the host and target.
And the FDTI module supports all RS-232 functions. All the other things I have seen only provide Rx/Tx.
I have been thinking of trying to put the USB/SP(serial port) code in a PDIP ATmega chip. I build as much engineering stuff as possible with PDIP chips. In wirewrap sockets.
My Arduino UNO board will not be here until early next week.

None of the Atmegas in PDIPs support USB tho, only the surface mount parts.
Can get a SMD to DIP adapter and make a socketable part that way.
I think I am seeing it now. The "U" means it has the USB interface.
I do have TQFP adapters.
The FTDI FT230X looks like a better choice. I can use it with my existing designs.
