Description Robinson Tiemuqinke 2005-06-28 19:45:22 UTC
Description of problem:
minicom can not send out 'ctrl-alt-del' 

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

How reproducible:
Every time.

Steps to Reproduce:
1. connect two PCs's serial ports with dumb terminal cable
2. one machine redirect its console to serial port
3. on the 2nd machine runs minicom on the serial port connected to first 
4. the 2nd machines can monitor the console output from first machine's 
kickstart, and key-in normal Linux commands without problems. 
5, But when trying to send 'ctrl-alt-del' from minicom, local machine 
intercepts the key combination and reboots. The 'ctrl-alt-del' can not be sent 
out to remote machine through minicom. Trying to send out '<ESC>R<ESC>r<ESC>R' 
key sequence doesn't help neither.

Actual results: 
local machine, which running minicom, intercepts the 'ctrl-alt-del' and 

Expected results:
'ctrl-alt-del' key combination be sent to remote machine through minicom; or a 
similar key sequence to sent to remote machine, and the remote machine 
interprets it as 'ctrl-alt-del'.

Additional info:
Seems not related to Redhat Linux Enterprise Linux only, it happens on Fedora 
Core as well.

It's like remote ssh/telnet session, ctrl-alt-del is traped by local
