Simple ascii char question

atekippe

I have a string that contains parsed data, specifically 4 ascii characters.· What I need to do is append an addition ascii character of my chosing ( char = 137 ) to serve as a termination indicator on·a·receiveing unit using Visual Basic 6.0.·· The characters must be sent as ascii format otherwise data gets lost in conversion. I'm sure it's a simple one line command but for some reason it has been eluding me.· Any help would be appreciated.

Hi

Couple of thoughts;
1) By reading from UART twice, and checking the data twice you will potentially miss odd characters.
2) To add ascii char 137 to a StringBuffer object use something similar - replace the code at the bottom of yours:

y=137; // append termination character to end of parsed string
buffer.append(char() y);
System.out.println( buffer.toString() ); // output string over JIDE Port on Javelin
buffnum=0; // reset position indicator
buffer.clear(); // clear buffer


Hope this helps,
