If you clone GitHub repositories using SSH, then you authenticate using SSH keys instead of a username and password. For help setting up an SSH connection, see Generating SSH Keys.

git config --global credential.helper wincred

Changing port parameters

To get current parameters

# stty -F /dev/ttyUSB0

speed 115200 baud;

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = ^J;

eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;

lnext = ^V; flush = ^O; min = 1; time = 0;

-brkint ixoff -imaxbel

-iexten -echoctl

To only get actual speed:

# stty -F /dev/ttySMX0 speed

115200

By default serial ports are configured as terminal emulator. If you want to use them as "raw" serial port you will have to do first (example for port 1):

# stty -F /dev/ttyUSB1 raw

# stty -F /dev/ttyUSB1 -echo -echoe -echok

To change baudrate of port 2 to 115200 :

# stty -F /dev/ttyUSB2 115200

stty -speed 19200 < /dev/ttyS1
stty -speed 19200 -f /dev/ttyS1

Sending/Receiving data

Send

# echo "HELLO" > /dev/ttyUSB0

echo -e "\x7E\x03\xD0\xAF und normaler Text" > /dev/ttyS0

The echo -e command enables the interpretation of backslash escapes.

To receive data (ASCII in that case):

# cat /dev/ttyUSB0
