This is actually a workaround Ter Term's issue of not obeying to the
telnet options that the server is sending. Therefore, we must buffer
chars until either a '\r' or the max length of the username/password
is received.
Unfortunately, these timeouts are the only realiable way (for now), to
be able to detect broken connections due to half-open sockets. Such a
thing occurs when getting out of the WiFi coverage area or when
disconnecting from the AP (sometimes the client doesn't send the
disconnect packet).
The port currently implements support for GPIO, RTC, ExtInt and the WiFi
subsystem. A small file system is available in the serial flash. A
bootloader which makes OTA updates possible, is also part of this initial
implementation.
