All settings can be changed during operation, no restart or power cycle is needed

Relaxed timing feature increases the MODBUS standard timing by a set factor.
This can be helpful for problematic master units. MODBUS protocol uses two time
restrictions per standard:
- t1.5 is 1.5x the character time at given baud rate and is the maximum time allowed
between two received character bytes before the whole received packed is out of
specification and considered bad.
- t3.5 is 3.5x the character time at given baud rate and is used for end of message
detection.
When relaxed timing is enabled by DIP switch, ProSMS uses this additional timing factor
located in RELAXED_TIMING register to extend t1.5 and t3.5 timing limits.

Settings can be additionally locked. When locked an accidental change of switches has no
influence on the configuration.
