There's no other party than dupterm itself in a better position to do this, and this is required to properly reclaim stream resources, especially if multiple dupterm sessions may be established (e.g. as networking connections). extmod/moduos_dupterm: Don't swallow exceptions in dupterm's read()/write(). 2016-04-13T13:34:11+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-13T13:26:29+00:00 urn:sha1:54ea253f5699c791ddff073b0193f257fa77cee1 The idea is that if dupterm object can handle exceptions, it will handle them itself. Otherwise, object state can be compromised and it's better to terminate dupterm session. For example, disconnected socket will keep throwing exceptions and dump messages about that. extmod/moduos_dupterm: Handle exceptions in call to dupterm's .write() 2016-01-01T20:06:38+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-01-01T20:05:30+00:00 urn:sha1:467504da01880bbe926f49ab777785dcee61d9a8 extmod/moduos_dupterm: Make mp_uos_dupterm_tx_strn() function reusable. 2016-01-01T14:43:35+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-01-01T14:41:26+00:00 urn:sha1:30b7344eb0a96c9cf608bec55ea38dfcb39ddfaf Function to actually spool output terminal data to dupterm object. extmod/moduos_dupterm: Make uos.dupterm() implementation reusable. 2016-01-01T11:04:32+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-01-01T11:02:53+00:00 urn:sha1:ddea7cb702db6ff350602b2bdd2193f149570060 That's just function which sets/gets dup terminal object, and can be easily reused across ports.
