Hi, I'm trying to write a Win32 app that prompts for a 3 character input and stores it in a variable for later use. However, so far I've got it to spawn a new console, write my text to the console, and then it doesn't seem to be waiting for input. My Perl in a Nutshell book indicates the ReadChar call from Win32::Console should be able to read a certain number of characters from the console, but it doesn't seem to be pausing for this input. Below is the code. All advice appreciated.

Thanks,

Glenn 

#!/usr/bin/perl

use Win32::Console;

$con = Win32::Console->new();

$con->Mode(ENABLE_WINDOW_INPUT,ENABLE_PROCESSED_INPUT,ENABLE_LINE_INPU
+T,ENABLE_ECHO_INPUT,ENABLE_PROCESSED_OUTPUT,ENABLE_WRAP_AT_EOL_OUTPUT
+);

$con->Display;

$con->Write("Please enter the agent ID number: "); # I want to wait fo
+r input here, but apparently the ReadChar below doesn't do that

@info = $con->Info();

$con->Write("The cursor info is ",$info[3],",",$info[4],". \r"); # Thi
+s presently prints no cursor data

$port = ($con->ReadChar(3,$info[3],$info[4]));

$con->Write("The port number to use is ",$port);
