Serial Comms and Visual Basic 5

26 Oct 2011

My project serial communication at 115200 baud works great with Hyperterm. With less that 0,5mS for a 50 byte message, but when talking to a Visual Basic 5 application the same message at the same baud rate takes almost 20 mS to transfer.

How should the VB application be set up to speed things up so that the hardware is setting the pace?
