Yes, I want an RS232 adapter. I'm progressing in my work to build a simple ML BBS program on the VIC (recreating my work from 1982) and I'd like to use Leif's BBS gateway program - he recommends the VIC-1011A.
It would be nice to have an AVR (Attiny2313 or a ATmega8) on the userport of my VIC instead of a VIC-1011A. An AVR could do all RS232 simply with internal UART.

Presumably these AVRs also support Ethernet (a lightning fast Google search suggests they do), so you could do everything on one board (no PC required!)
Userport connector on one end, R-45 Jack on the other. Writing some RS232 to serial conversion code (or port tcpser, etc) would be relatively easy.

Yes, exactly this is my intention.
Not only Ethernet, USB and RS232. Many things are possible easily with an AVR on the Userport: IEEE-488. I2C, digital IO, analog in ...

I picked up a freeduino and a ethernet shield to make a cheap serial server, but the serial libs have NO HANDSHAKING!. Kinda put a damper on my plans. Works great on a pc, like butt on a slow computer.
To answer your original question: Jay a.ka. Doppleganger makes and sells RS-232 boards designed by Jim Brain. There are two versions, one which emulates a Turbo 232 on the C64 cartridge port, or one that basically performs the same as a VIC-1011A on the user port (VIC or 64). The latter is the one you want, I forget the name.
