Asynch Properties
IEC 60870-5-101 protocol octets are transmitted as 8 data bits, 1 stop bit, and even parity. As
for all serial protocols, the ASE2000 sets these parameters as defined by the protocol but allows
them to be changed (primarily for device consistency testing). Sending a message after any
parameter is changed will cause a data reception error at any compliant device
