Need help with reading string from USB port	Can't Post

Hi all,

I'm quite new in PERL and would like to ask how am I going to read a string from a USB bar code scanner on every scan and save it directly to a text file for further manipulation? The scanner originally will emulate keyboard input upon every read and include a carriage return after every read.
Please kindly help, thanks.

I'm also a beginner but maybe i can help you with this;

Code

open (OUTFILE, '>>D:\data.txt');  
 
$userinput =  <STDIN>; 
#chomp ($userinput);  #optional 
print OUTFILE "Code:  $userinput\n"; 
 
close (OUTFILE);

Let me know if I'm completely wrong

Thanks a lot. It works for me. I'm currently working on the program flow. Will update my question once I face new issue.
