Description Kaj J. Niemi 2004-01-28 14:48:08 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):
2.6.0-1.61

How reproducible:
Always

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)
  
Actual results:
Doesn't seem to do anything but _something_ is sent over the wire as
the lights do blink

Expected results:
Cisco should drop to rommon, sun to openboot :)

Additional info:
See bug #112889 and bug #113700 for more information regarding mct_u232.
Comment 1 Pete Zaitcev 2004-08-19 19:41:09 EDT
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)
