mct_u232: sending break doesn't have any effect
Last modified: 2007-11-30 17:10:35 EST
Description of problem:
Sending a break from minicom (or kermit) with kernel 2.6.0-1.61 fails
using the mct_u232 driver on /dev/ttyUSB0.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. connect your usb<->rs232 converter to equipment expecting a break
(Sun server, cisco router/switch, etc.)
2. start minicom
3. hit break (in minicom ctrl-a f) when the connected equipment is
expecting it (eg. for a cisco when you want to drop to rommon for
password recovery or similar activity)
Doesn't seem to do anything but _something_ is sent over the wire as
the lights do blink
Cisco should drop to rommon, sun to openboot :)
See bug #112889 and bug #113700 for more information regarding mct_u232.
Unfortunately, there's no easy way to add break to mct_u232.
It's a driver based on reverse-engineered code.
I suggest turning to Keyspan (or Edgeport).
Closing with WONTFIX (should be CANTFIX)
