- Keywords: serial driver bugs 0.99.2 0.99.4
-
- The 0.99.2/3/4 serial drivers have a set of bugs to do with CLOCAL, these
- prevent several programs that should work from working on lines without
- the carrier signal present. When the terminal is opened the line is marked
- as hung_up and when CLOCAL is then set the line is not restored.
- In addition the serial driver doesn't block until carrier is raised in
- normal use as Unix systems do.
-
- I've posted Linus a set of patches a while ago for this and 0.99.2 , but only
- for the new interrupt handler, these also allow you to select() on a tty
- open like the sys5.4 terminal managers do.
-
- In the meantime a warning for anyone using the amateur radio KA9Q version
- I released. DONT upgrade to 0.99.2 without the serial patches I included
- and DONT upgrade to 0.99.3 or .4. I'll try and merge the serial fixes into
- the 0.99.4 kernel and resubmit them again.
