Serial Port Communication in C# using sPort_DataReceived() event

In an application of:
Serial Port Communication in C# using sPort_DataReceived() event

I have noticed that the maximum number of characters that you can receive using this event is limited to 8, and if you try to receive a string having more number of characters, it receives the first 8 characters in the first Timer tick, and than receives the rest in the second timer tick.

İs it possible to receive the complete string at once (say a string of 16 or 20 characters) and whta are the actions to take for this

8 bytes sounds like a pretty standard (albeit small) hardware buffer for a UART.
(I work on systems with a 4byte buffer)

A key tip about the SerialPort class I have found:
Do as little as possible in the EventHandlers, you'll thank me for it later when you're not dropping bytes.

I had it setup so that the dataReceived() event only set a boolean that told a Timer.Tick() event to read data and push it into a software buffer (An arraylist maybe or some other dynamic allocation object)
Then I was no longer dropping bytes and they were all there ready for me.

Thanks very much for the useful tip Platter, I shall try and let you know of the outcome
