 - To automatically start t38modem, you need to create Systemd services, as well as start and stop scripts

+#### Quick script overview
+- Using that script, it is possible to `start` or `stop` the emulated modem.
 - `-t` enables debugging
   - More `t`'s is deeper debugging (e.g. `-tttt`)
 - You can of course run the t38modem command without this init script
 - If t38modem says it was able to create the virtual modem but `/dev/ttyT38-1` is not available, you do not have sufficient permissions
 - Configuration is specified in `/etc/t38modem/config`

+To do this you have to copy paste the following into `/etc/systemd/system/t38modem.service`.
