Description Ian Laurie 2007-08-15 21:28:09 EDT
Description of problem:
I have been using an Edgeport USB/Serial adaptor and set RTS using this

    bits = TIOCM_RTS;
    ioctl(GenInfo->fd, TIOCMBIS, &bits);    /* Assert RTS */

This has worked on all FC6 kernels up to and including kernel-2.6.20-1.2962.fc6.
I updated to kernel- yesterday and the above code no longer works
with the edgeport device driver.  The function call returns zero, but RTS does
not get asserted.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  See code above.
Actual results:
Function returns zero but doesn't do anything.

Expected results:
RTS should be asserted as it was with previous kernels.

This is apparently fixed by git commit bc71e479cdb2caab9b4473f7ad508c3fcb142486.
Will get in kernel as soon as possible but today's build is already running.
Comment 2 Chuck Ebbert 2007-08-16 13:37:12 EDT
Fix is in already. Try from the updates-testing repo, or
wait for the next kernel update.
Comment 3 Ian Laurie 2007-08-23 20:18:26 EDT
The kernel- update seems to have fixed it.
