Linux: Serial Port Communication
Posted: 25 Nov 2014, 6:18am - TuesdaySince HyperTerminal was removed in Windows 7, I decided to look up on Linux tools for serial port communication and found minicom command. Here's how to install & use it (in my case I used Linux Mint):

# apt-get install minicomThen after installation, cast a command:
# minicom -s +-----[configuration]------+ | Filenames and paths | | File transfer protocols | | Serial port setup | | Modem and dialing | | Screen and keyboard | | Save setup as dfl | | Save setup as.. | | Exit | | Exit from Minicom | +--------------------------+Then you have to setup the serial port,
+-----------------------------------------------------------------------+ | A - Serial Device : /dev/ttyUSB0 | | B - Lockfile Location : /var/lock | | C - Callin Program : | | D - Callout Program : | | E - Bps/Par/Bits : 9600 8N1 | | F - Hardware Flow Control : Yes | | G - Software Flow Control : No | | | | Change which setting? | +-----------------------------------------------------------------------+So in my case, I used USB to Serial connector, so I set Serial Device to ttyUSB0 After that, go to Exit and you'll be connected to the device you want to connect like Cisco routers/switch.

When my friend's Card Reader goes something wrong, I tried to fix it and found that the wires are pulled out. So I found the solution (shown below) to resold the wires back into its position.

Pin one side | Signal | Description | Pin other side |
1 | USB Vcc (Vbus) | usually RED, wire should be 20-28 AWG | 1 |
2 | USB Data - | usually WHITE, wire should be 28 AWG | 2 |
3 | USB Data + | usually GREEN, wire should be 28 AWG | 3 |
4 | GND | usually BLACK, wire should be 20-28 AWG | 4 |
