1. I'm just experimenting with your software - do I need a license?

No, so long as you have a copy of the 'TCP/IP Lean' book. We encourage our customers to evaluate our software, by experimenting with it prior to making a commitment to use it commercially. Students may use our software in non-commercial projects, so long as the copyright notices are retained.

2. I'm using your software in a commercial application - do I need a license?

Yes. You should obtain a license from Iosoft Ltd., see www.iosoft.co.uk/license.php for details

3. What is an 'unlimited-incorporation' license?

Each time you incorporate a binary image derived from the Iosoft source code into a product item, it is known as an 'incorporation'. The Iosoft licenses are 'unlimited-incorporation'; once your organisation has a license, it may embed an unlimited number of binary images, in an unlimited number of products.

4. What do you mean by a 'binary image derived from the Iosoft source code'?

A compiled version of a program that includes Iosoft source code. Normally, you will be adapting and extending the Iosoft source to customise it for a specific application, then compiling it into an executable binary image (e.g. a HEX file), which is then blown into ROM, or directly programmed into a microcontroller.

5. Does the unlimited-incorporation license allow the distribution of binary images?

Yes. You may distribute hardware products containing binary images, or the binary images (HEX files) themselves.

6. What about source code?

No. The redistribution of Iosoft source code is expressly forbidden.

7. My customers require source code - what can I do?

Document which version of the Iosoft code you have used, and any changes you have made to the source. If the changes are substantial, it may be necessary to use an automated file-difference ('diff') software tool.

If your customer wants to re-compile the source, they must purchase the original source code and a commercial license from Iosoft.

If your customer needs the source code purely for archive purposes, and is only using binary images you have supplied (they are not creating their own images), then they do not need a commercial license.

8. I'm a consultant - do I need a commercial license for each of my customers?

No. One commercial license covers you for distributing binary images to an unlimited number of customers.
