In canonical mode, input is made available line by line. We must stop
the canonical buffer filling upon reception of an end-of-line character.
Close#3218.
- Remove the printf support leaving the direct printk support configured
with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
call to printk.
- Control the test's single init for functions and global data with
TEST_INIT and not CONFIGURE_INIT. They are now separate.
Updates #3170.
Remove obsolete support for OFILL, OFDEL, NLDLY, CRDLY, BSDLY, VTDLY,
and FFDLY which is not present on FreeBSD and not implemented in Linux.
Update #2833.
Currently only blocking read/write operations are implemented. A
blocking write must transfer at least one character. It should not wait
for the device for the second character and so on.
Close#2917.
Call the receive callback in case a read will succeed without to block.
This enables the use of the receive callback for a poll() and select()
support. Increase raw input buffer size to allow buffering of one line.
Close#2916.
In case carriage return characters should be ignored in the input
(IGNCR), then drop them early before they reach the raw input buffer.
This makes it easier to calculate the content size of the raw input
buffer.
