 Posted: Sun Jul 27, 2003 1:49 pm Post subject: Can't echo to router /dev/ttyS0 after reload/quit! |
 |
|
I have this shell script, that runs:
1. write erase
2. reload
3. answers "no" for the configuration dialog question
4. enable
5 some more commands..
All the writings to the router are echo $1 > /dev/ttyS0.
After step 3, the script commands no longer reach the router!
I have to enter minicom, press Enter, and quit minicom (without "quit"
command. only CTRL-A-q).
It seems as if i enter minicom, type "quit" (and get the "press return
to get started" print), and exit minicom without hitting enter, I
encounter the same problem.
btw, echo-ing "enters" doesn't do the job either.
Does anyone have a clue?!
i'm using a cisco 26xx with ios 12.2. |

If so, make sure you use setserial command to set 9600,8,n,1 no flow
control. Some PCs have a tendency to set flowcontrol on when the routers
lowers/raises the DTE on the COM port.
