To-Do list for project SMSLink==============================(Last modified on 28/07/99)* Clean code (add tests after each malloc)* Improve Makefiles* Might be needed to add "routing help" for specific routes. More on  this after some testing.* Solve this "char" versus "line" mode problem in telnet* Improve the procedure that will save the incoming messages to file.  Currently, messages might get lost in the following scenario: if  the mailbox file is locked (by another application) when the server  tries to save the messages, an error is issued but the server doesn't  retry, it just goes on and happily removes the messages from the SIM,  meaning they're just lost.* Improve parsing (we should use a separate procedure to get the  commands, then parse them one at a time)* Improve variable handling (and typing) in the parser.* Add "validity period" handling for the SMS messages. There should  be a configurable application-wide default value, and a command  supported by the parser for the user to override this default.* Add command line parameters handling in the server (listening port,  interval between incoming messages checks, ...).
