I don't believe the data in the config file is either encrypted, or in a strange character set we don't get- for me, config files (for simple, non-protected data) are always in tokenized form, In other words, token followed by value. Repeated pairs, usually preceeded with a count of pairs or terminating with an end marker token, thus allowing saving of multiple profiles and allowing selection of one or more by simply reading through until you hit the version you want.
Unfortunate on two counts, as 1) I'm totally wrong- in which case apologies. 2) The interpreter that reads the config file and inserts the data knows the tokens, knows the format of the contained datastring, and will interpret as needed.
May be worth investigating though? Rather than trying to read the file through a simple text reader, hex editor or translator?
In the end though- I now have tty access from the config file given earlier (second draft) although SH access is spotty- only every second command works? (I am using windows though - maybe my tty encoding is wrong over PuTTY)
