This is not reading from the port. You cannot do 2 redirections. You're attaching stdout to /dev/ttyS0 but immediately changing that to a file called bla.
Code:
mute@thedoctor:~$ echo hi >file1 >file2
mute@thedoctor:~$ ls -l file?
-rw-r--r-- 1 mute mute 0 Oct 19 21:29 file1
-rw-r--r-- 1 mute mute 3 Oct 19 21:29 file2
This shows how redirection to two places fails. You only need to:
Code:
$ echo W >/dev/ttyS0
$ cat /dev/ttyS0
Try to set permissions, as root, to allow everyone access to the serial port with chmod 0666 /dev/ttyS0. If your code then works, the issue is that the webserver doesn't run as ethan, but another user who doesn't have access to ttyS0.

mixerctl.conf
MIXERCTL.CONF(5) BSD File Formats Manual MIXERCTL.CONF(5)NAME
mixerctl.conf -- audio mixer configuration file
SYNOPSIS
mixerctl.conf
DESCRIPTION
The /etc/mixerctl.conf file consists of mixerctl(1) variables to set at boot time. Each line of mixerctl.conf has the following format:
variable=value
To generate a mixerctl.conf from the current mixer settings, execute:
mixerctl -a > /etc/mixerctl.conf
Set mixerctl to YES in rc.conf(5) to have the variables set at boot time. Additionally, you can have the settings saved and restored for the
devices of your choice by listing them in mixerctl_mixers in rc.conf(5).
