TheWire13 is a TCP/IP stack for classic Amiga systems running
AmigaOS 1.3.

The project was written specifically for low-level AmigaOS networking
experiments and real hardware usage on systems without modern TCP/IP
stacks available.

TheWire13 currently provides:

* SANA-II networking
* ARP
* IPv4
* UDP
* TCP client connections
* DNS resolver
* ICMP Echo (Ping)
* DHCP client support
* bsdsocket.library compatibility layer

The stack is intended to provide a lightweight and OS1.3-compatible
networking environment for custom tools and applications.

## Current Status

THIS IS AN ALPHA VERSION.

TheWire13 is still under active development and internal structures,
network behavior, and APIs may change between releases.

At the moment the stack has only been tested with:

* a314eth.device (Thx to Niklas)
* enc62413.device (Zorro-LAN-IDE-CP Card)

Other SANA-II drivers may or may not work yet wich primary depends on 
OS 1.3 compatibility.

The stack is considered experimental software and should not yet be
expected to provide the same stability or compatibility as mature Amiga
TCP/IP stacks such as AmiTCP, Miami, Genesis, or Roadshow.

## Requirements

* AmigaOS 1.3
* SANA-II compatible network driver
* at least 68000 CPU (>=68020 recommended)
* enough free RAM for networking buffers

## Installation
copy TheWire13 to C:
copy bsdsocket.library to LIBS:
copy amitcp13.conf to S:
copy all mini_* programs to C: (e.g. mini_ping)

For Zorro-LAN-IDE-CP Card:
copy enc62413.device DEVS:networks


## Configuration

The stack currently uses the configuration file:
S:amitcp13.conf

Example options:

device = a314eth.device
unit = 0
dhcp = 1

or static configuration:

device = a314eth.device
unit = 0
dhcp = 0
ip = 192.168.7.16
netmask = 255.255.255.0
gateway = 192.168.7.1
dns = 192.168.7.1

## Starting

Start the stack from Shell:

## Notes

* The stack binary itself is intentionally kept lightweight and avoids
  large stdio/newlib runtime dependencies.
* DHCP support is integrated.
* bsdsocket.library support is still incomplete and evolving.

## Known Limitations

* Alpha quality software
* Only limited SANA-II driver testing so far
* Primarily focused on TCP client usage
* Long-running/high-throughput transfers are still under investigation

## History

1.1
- Added AMITCP13_SOCKET_CLEANUP_DEBUG=1, which enables socket cleanup/pool diagnostics. 
- Added fd/socket/TCP/UDP/RAW pool summaries behind debug builds. 
- Hardened TCP cleanup for stuck CLOSED, FIN_WAIT_1, FIN_WAIT_2, CLOSING, and LAST_ACK PCBs. 
- Cleaned failed initial SYN send path without prematurely reusing the socket wrapper.

1.0
- Added central limits in include/amitcp13/socket_limits.h. 
- Increased core/IPC socket slots from 8 to 16. 
- Increased TCP PCB pool from 8 to 12.

0.9.1
* Improved RX speed on enc62413.device by factor 10
* Bumped Mini_FTP_Gui to v0.4
  - mini_ftp_gui now tracks the PASV data socket with a single g_data_fd.
  - Before every new PASV data connection, any previous data socket is closed.
  - LIST/GET/PUT close data sockets on success and error paths, then wait for final 226/250 replies where appropriate.
  - Ambiguous transfer failures now close the control session and show reconnect-required status.

0.9 Alpha
* Improved stability
* Introduce the new enc62413.device
* Reduced debug output

0.8 Alpha

* Public runtime renamed to TheWire13
* DHCP support added
* ICMP support added
* TCP throughput improvements
* Reduced memory footprint / stdio-free runtime
* Improved network recovery stability
* Expanded bsdsocket.library compatibility
