Jay,
>I'm not sure I understand much about the bytesTotal and tnByteCount. Is this something I'm calculating and then passing? When I use the OLE (MSWinSck.ocx) it doesn't care how much I send it.
No, is not something you need to calculate. When the event DataArrival is fired, it receives in the bytesTotal parameter how many bytes have just arrived, so you can dimension your strData variable to accomodate all of them. In your case, what would happen if you receive 257 characters? It might just discard the last one, or it might generate an error, I do not know. On the other hand, if you just receive 2 characters, you are going to end up with 254 extra trailing blanks that were never received.
