$ls -l /dev/[serial device]

./connect.sh /dev/[serial device] [baud speed]

$./connect.sh /dev/ttyUSB0 19200

# connect.sh


#Taken from example modified by: ihatetoregister
# On stack exchange, thread:

# Modified by Rafael Karosuo <rafaelkarosuo@gmail.com>
#   - parity enabling and amount of stop bits
#   - no execution without minimum params
#   - exit code for stty
#   - bgPid fix, used $! instead of $? to take the PID of cat proc in background.
#   - exit command to end the program
#   - CR termination and strip of NL added by READ command, in order to make $cmd\r\n format instead of \n$cmd\n


# Usage:
# $./connect.sh <device> <port speed> [# Stop bits] [parity]

# Stop bits 1|2
# Parity even | odd

# If no last two params, then default values stopbits=1, parity=disab

# Example: 
# connect.sh /dev/ttyS0 9600 1 even, this will use 1 stop bit and even parity
# connect.sh /dev/ttyS0 9600, this will take default values for parity and stopbit


#Check if at least port and baud params provided
if [ -z "" ] || [ -z "" ]; then
