I think he wants to use the tape port exclusively.  To me, that causes 
issues because you're essentially using the PC as a large tape drive, 
but the real tape drive had REW/FF/PLAY/RECORD as manual buttons.  In 
essence, the computer operator performed a manual DOS function.  You can 
do little more as a PC.  The IEC bus offers the ability to implement a 
complete DOS on the PC, including directory listings and such.

I can;t comment on the TINY2313 C2N232 implementation, but I have a 
working ATMEGA16/32 IEC implementation with a working file server 
written here that uses the PC serial port.  I'm still fighting a bug in 
the JiffyDOS implementation during loads, and there's a myriad of DOS 
commands like U0> and such left to implement, but the former is fixable, 
and the latter is just code I need to write, no technical challenges.

It works very nicely, though a bit slow.  As when I started the project, 
I intend to get the packet structure and such working and robust over 
serial, and then migrate to a USB-based AVR device and port just the 
packet system and my file server code to USB.  That should remove speed 
issues.  Though, with JiffyDOS turned on now, I get 4000bytes/sec, which 
is not too shabby.

The server is platform independent, and has no GUI.  It is controlled 
completely via the IEC bus command channel.
