Minicom help
 

I'm trying to connect to a Cisco router (1711) via console cable.

I can connect to it via Minicom and can see the output on the screen fine but I can't seem to send any data to it.

The last line I see is "Press ENTER to get started" and I hit enter a hundred times and nothing happens.

Yet...when I use GtkTerm it works fine.

IS Minicom configured correctly ?

Enter minicoms setup mode by using the s switch like so:

minicom -s

This will bring up the minicom configuration menu.
Select "Serial port setup" using the arrow keys and press Enter.
Press "A" to change the Serial device from /dev/modem to dev/ttyS0.
Press "E" to change the Bps/Par/Bits, then press E again to select 9600.
Press "F" to turn off Hardware Flow Control.
Hit Escape key to leave configuration menu,
arrow down to "Save setup as.." and save this entry as "cisco".
Once configuration is saved,
arrow down to "exit" at which point minicom will connect to the Cisco router and You should see the router> prompt.

If some of the Serial port settings are incorrect that could be the cause for you to be unable to send data.
Cisco console port settings are

9600 baud
8 bits
N - no parity
1 - stop bit
N - No Flow control
