I now more or less finalized the serial API code, just need to make sure it's no serious bugs in it.

Due to lack of program space (I filled 93% of the 32K I have available) the serial API does not have much of validation or smartness so if you enter same rotor in all position it will accept it.

Sample run

A session from power on, config, encrypt and decrypt
Lines starting with
"!" = command I send
"%" = replies to commands
"#"= comment
A-Z=text to encrypt/decrypt
> the result
Setting loglevel to 1 means show how the encryption is done trough all the rotors

With the presets it's easy to do things like keep the settings for different networks or a few daily settings and then use them when for example encrypt/decrypt messages on http://enigmaworldcodegroup.freeforums.net/
