>I have a program that reads the serial port for data sent by an external device. I do this using a timer that calls a DLL function every N miliseconds (in this case we are using values from 10 to 50 milisecons). Based on the data received from the serial port, a set of function is called and some SQL commands are executed using ODBC (the connection was previously opened). My problem is that while the ODBC command is executing (it takes around 5 seconds because there are triggers that update a lot of tables), no access is made to the serial port, and that causes some sluggish performance when there are too much data to read.
