Fastest speed through Serial port?(RESOLVED)

Dear .NETers,
I have a project where I am trying to read in binary packets from the serial port. These packets are sent from a PIC controller. This 16 byte packet is sent at 250 hz even at 57600 baud with a 1.2 milisecond pause between packets. Has anyone been able to receive data this quickly using VB.net? If so, do you have any code examples I can look at. I know that vb was considered very slow but machine are much faster now and we now have VB.net.

I basically want to read these binary packets into a database and also be able to display them on a stripchart.

Thanks in advance,
Bebandit

Hi,

To communicate with the Serial Communication Port without using back the MsComm then you have to use the P/Invoke method to develope the base class event.

Please refer to the link below for the source code and the article, but it is in Visual C#.Net.

in microsoft download centre, there is 101vbnetsamples.zip file, having 101 vb.net samples. one sample is based on COM port
