I can't get proper output on my POS Pole Display using my Visual Basic<br />
<br />
In QBasic, I type<br />
&nbsp; &nbsp; &nbsp; Open &quot;COM1:9600,N,8,1&quot; for output as #1<br />
&nbsp; &nbsp; &nbsp; Print #1, Chr$(12)<br />
&nbsp; &nbsp; &nbsp; Print #1, &quot;123456789&quot;<br />
&nbsp; &nbsp; &nbsp; Close<br />
It would clear screen and add the string on display<br />
<br />
but in Visual Basic, when I type<br />
&nbsp; &nbsp; &nbsp; Open &quot;COM1&quot; for output as #1<br />
&nbsp; &nbsp; &nbsp; Print #1, Chr$(12)<br />
&nbsp; &nbsp; &nbsp; Print #1, &quot;123456789&quot;<br />
&nbsp; &nbsp; &nbsp; Close #1<br />
it comes out only unknown symbols.<br />
<br />
Is there any mistake on the VB Coding? I was to execute the code in Hex &nbsp; &nbsp;1B 51 41 n OD &nbsp;to write string n to the upper line. <br />

Command for POS Display

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
