This task is infact MUTCH more complicated than you can
imagine.
First you have to program the serial chip to
send and receive bytes when sertain amount of bytes
have been put in its buffer. The serial device driver
can also been programmed to timeout if the buffer is
not full. Then you have to consider this for booth outgooing
and incomming characters.
I recommend that you read chapter 18 "A modem dialer" in "Advanced Programming
in the UNIX environment" ISBN-0-201-56317-7. g_unix_input_stream... works good for
a TCP/IP stream but NOT for hardware oriented stuff.

Hi,
i'm writing an app which used to auto test AT commands...
i open fd with the /dev/ttyS0, and pass it to g_unix_input_stream_new
the qustion is how read the buf as line by line ?
because of the buffer size is 4K, if directly use g_data_input_stream_read_line, it will block forever,
and then i use g_buffered_input_stream_set_buffer_size to change the buffer size to 1 byte
it works, but it should be not efficient
and good ideas for this ?
thanks, and sorry for my bad english....
