Byte by byte. Either as byte array or as string.

Hi  rajeshavyas;

What I think you are looking for is first to convert all your control codes such as <SOH>, <LF>, <STX> and so on to their ASCII code values. For example <SOH> is Start Of Heading which has a numeric value of 1 and <LF> which is Line Feed and has a value of 10 and everything else represents itself. Place into a Byte array or a string like this.
Dim sendThis = Chr(1) & Chr(10) & "09_Cobas_Integra_09" & Chr(10) & Chr(2) & "10_01" & Chr(10)

Open in new window

Although I do not know what <EFX> is? It may be a device specific code. Below is the beginning of the ASCII table that has the control codes. You may need to add a reference to Microsoft.VisualBasic.dll and use the Imports Microsoft.VisualBasicASCII Control Codes
