Thanks for your answer. Can you show me with an example or where do I need to change it in my code.

Thank You Maciej Los. thanks to your idea I've fixed the code. Code 1 now working fine.

AddHandler b.Click, AddressOf printPreview_PrintClick

Works in two ways.

Dataflow examples for Protocol version 1
HCTS -> LIS <STX>·····D·BI01234ABC567830500000;3<ETX>

Dataflow examples for Protocol version 2
HCTS -> LIS <STX>·····D·BI|1234ABC5678|30500000|?7<ETX>

But the checksum is different. Probably included in the calculation. Protocol 1 using 0 ZERO
Protokol 2 using | pipe

My head mixed well :(

..... Filled with blanks ( Space by number of dots )

| divider. Pipe symbol ASCII 0x7C (I'm not sure about this) There is no information on the article about it

As an example, the calculation of that sequence. Please include all codes. Thanks.

<STX>.....D.BI|1234ABC5678|30500000|?7<ETX>

Yeah you worked your code right. You are right. I had to ask this question in another topic.

thank you for your help. The code is working correctly. But there is one point I do not understand. can you help me. There is an article on the elimination. According to this article I can not find Checksum. Here are a few examples and articles;

2.1 Framing

Each data transfer takes place within a frame. Each data packet has the following structure:
<stx> FL FN FI [DATA] Checksum <etx>
<stx> 1 Byte (02hex) Start of frame
FL 3 Byte Frame length, not used currently, filled with blanks (20hex)
FN 2 Byte Frame number, not used currently, filled with blanks (20hex)
FI 2 Byte Frame identifier, only ‘E’, ‘I’, ‘D’ and ‘S’ used for 1. Byte
currently, 2. Byte always blank (20hex)
[DATA] Application data (if present)
Checksum 2 Byte Checksum
<etx> 1 Byte (03hex) Frame termination

2.2 Error detection and flow control
In order to ensure data integrity, a checksum is transmitted with each frame. This checksum
is calculated by adding the values of all transferred bytes from <stx> to [DATA] (both
inclusive), modulus 100hex. The sum is devided by 10hex. 30hex is added to both the
quotient and the remainder of the division. The results (ASCII ‘0’ to ‘?’) represent the 2-
character checksum. For example, the sum 3f9hex will result in “?9”.

Communication Log;

HCTS -> LIS <stx>.....D.BI|1234ABC5678|30500000|?7<etx> --- Checksum ?7
LIS -> HCTS <ack>
LIS -> HCTS <stx>.....D.DW|1234ABC5678|||CHOL....BILI_TOT|5=<etx> --- Checksum 5=
HCTS -> LIS: <ack>

HCTS -> LIS <stx>.....D.BI|1234ABC5678|D050000F|1><etx> -----Checksum 1>
LIS -> HCTS <ack>
HCTS -> LIS <stx>.....D.BI|9555907034|A000000B|;7<etx> ------Checksum ;7
HCTS -> LIS <stx>.....D.BI||A000000Z|<0<etx> ------- Checksum <0

Not: ..... = blank

I did not calculate the check. Where am i making mistakes.

My aim is to save all the data files in the TextBox on form2. But I can not access the data that I wrote out form1. Even if the data does not show, as I wrote in the above example.
