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.
