Very Good

This app does what it claims and I have so far found it to be stable, reliable and very helpful.

I already have a very good diagnostic app on my device with a terminal but still find this dedicated terminal app preferable when I need a terminal. Its keypad is great and explanation of the AT commands for the ELM327 are very helpful.

I have read the ELM327 data sheet and the AT commands quick guide and still found the in depth explanations in this app for AT commands to be very useful. It will give you a good understanding of them.

I have a few feature requests.
1. Regarding the keypad, could we have the option to have full A-Z so we can enter AT commands rather than searching and selecting them. A press and hold on an existing character to get a pop up of unavailable characters could be nice?

2. Favourite Commands List.
Send one or more commands. If it's a multiple command to be sent we get a a button to send the next command so the user can check the response from the ELM327 before the next command is sent.

Thanks for a great app :)
