mCore™ .NET SMS Library 1.2

Thread Safety

All properties of mCore classes (of a particular instance of mCore.SMS) can be written in to or read from, simultaneously from multiple threads without raising any exception. However, the results of doing so are not guaranteed in terms of producing the desired results.
All methods of mCore classes (of a particular instance of mCore.SMS) can be called simultaneously from multiple threads without raising any exception. However, the results of doing so are not guaranteed in terms of producing desired results.
All properties and methods that require serial communication with the GSM Modem are queued internally by mCore.SMS instance and will never cause serial communication errors. In other words, Sending SMS from multiple threads using the same instance of mCore.SMS (with same value for serial communication properties viz. BaudRate, Port etc) will work perfectly alright as the commands from various threads will be queued inside mCore.SMS instance. To get desired results, changing of properties like LongMessage, Encoding, Validity, SMSC etc should be avoided from multiple threads.
Using multiple instances of mCore.SMS with each instance connected to a different serial port (i.e. having different Port property) is completely thread safe.
