Hello,
I don't know using which component to control serial port on Device. The OS runing on device is WindowsCE 4.2 and .NET compact frame work 1.1. I added reference System.IO but not found class SerialPorts in this package. Can you help me solve this problem Thanks for your help.

Hi Steven
Windows CE 4.2 support was added with .NET CF 2.0 SP1.
No, you cannot use VB.NET 2003 - you'll have to use VB.NET 2005.
Find some more infos on serial port with .NET 1.0 here: Serial Communication with the .NET Compact Framework

NETCF V1 (there’s no NETCF 1.1) has no serial port support. You could use OpenNetcf.org implementation or upgrade to NETCF 2.0.
