- Debian/Ubuntu based distros:
sudo apt-get install minicom
- Red Hat/Fedora based distros:
sudo yum install minicom
- Check whether your serial port is detected by the kernel:
dmesg | grep ttyS
[ 0.485378] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 0.485739] 00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
- Run Minicom:
- Press Ctrl+A Z to enter Minicom’s menu.
- Press O to enter configuration submenu.
- Enter the serial port setup.
- Set the serial device (/dev/ttyS0 in this example).
- Press E to set the “Bps/Par/Bits”.
- Press C (9600 bps) and Q (8-N-1).
- Set software flow control to NO.
- Save the configuration as “cisco” (for example)
- Press Q to quit Minicom
- Run Minicom with the new configuration:
sudo minicom cisco
Tip: if you need to send a “Break” through Minicom (on a password recovery operation, for example), use Ctrl+A F or do the normal exit key sequence (CTRL-a, x).
