Here's a step-by-step set of instructions on how to console onto your cisco router or switch from your mac using minicom. Install minicom via Fink Fink minicom page. In the Terminal, type fink. Jun 23, 2017 About the App. App name: minicom; App description: Menu-driven communications program; App website: Not Available; Install the App. Press Command+Space and type Terminal and press enter/return key. The best program I know of for this is minicom, available from Homebrew, fink, and macports. Minicom is a serial communication program. It is a Unix clone of the well-known MS-DOS Telix program. It has ANSI color, a dialing directory, dial-a-list, and a scripting language. Minicom-MAC OS使用串口调试交换机的利器. 换了mac os之后本来使用串口调试交换机都是使用虚拟机上的SecureCRT来调试的，可是每次都要打开虚拟机有些繁琐。并且SSH都可以用终端来调试特别简单，干脆，所以也就想着能不能直接使用终端来通过串口调试交换机。.

If you need to connect your linux server to a cisco device through the serial port this is the best way to do it. This guide is for Debian/Ubuntu but will work with any linux distribution.
First you need to install minicom this is easy using apt-get or yum, just do the following command.
> apt-get install minicom
Once installed you need to find out what your serial port connection is.
> dmesg | grep tty
Minicom Configuration File
Output:
[ 15.453264] console [tty0] enabled
[ 17.339818] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 17.340257] 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
The seial port in this example is at /dev/tty0

Next configure minicom to use that serial port and connect to the cisco device.
> minicom -s
Minicom For Mac
Choose serial port setup, change the serial device to /dev/tty0, change the Bps/Par/Bits to 9600 8N1. Now choose save setup as… and change the name to whatever you like, for example cisco, now save and exit from minicom.
To use this configuration use the following command.
> minicom cisco
Now the serial connection should open up and it will be connected with the cisco device.

Minicom is a menu driven communications program. It emulates ANSI and VT102 terminals. The current version is 2.4, from 2009-12-20.
Installing it on Mac OS X is quite easy, thanks to the MacPorts (formerly Darwin Ports) mechanisms:
$ sudo port install minicom
The result is /opt/local/bin/minicom, and, if MacPorts were installed properly, should already be in the PATH.
Before using minicom, the default configuration should be created:
$ sudo touch /opt/local/etc/minirc.dfl
$ sudo minicom -s
Additional configurations can be created, for example by saving the default configuration to a configuration with another name, for example dbg. The serial port is stored in the configuration, so it is not needed to specify it every time.
Further use of this new configuration is possible by refering to the given name:
$ minicom dbg
