Hi, I'm using the TTY driver with CR/LF translations for console IO. When I write a single '\n', I get the assertion failure below: ASSERT FAIL: <4>stream.inl [ 179] Cyg_ErrNo Cyg_StdioStream::write_byte() Single byte not written, but no error returned! The tty_write() routine translates the '\n' into '\r\n' and thus returns 2 which confuses the Cyg_StdioStream::write_byte() routine. I believe that tty_write() should return the number of bytes consumed and successfully passed to the underlying device. The attached patch proposes a possible modification to tty_write() and a ChangeLog entry follows just in case ... Robin 2002-02-25 Robin Farine <robin.farine@terminus.org> * src/common/tty.c (tty_write): Instead of the number of bytes actually written (which may include extra bytes due to e.g. CR/LF translations), yields the number of bytes consumed from the caller's buffer and successfully passed to the underlying output channel.
