           Summary: Keyboard echo erratic when using TermInfoDriver
                    console input
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.6.x
          Platform: x86
        OS/Version: Mac OS X 10.6
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: CORLIB
        AssignedTo: mono-bugs at lists.ximian.com

Keyboard echo is erratic (not to mention sluggish) in both Linux and Mac OSX
when the TermInfoDriver is being used as a console driver (which is almost
always the case in normal situations). As an example:

$ cat Repeat.cs
using System;

class Repeat
{
    public static void Main(string[] args)
    {
        Console.Write("Say something: ");
        string saying = Console.ReadLine();
        Console.WriteLine("You said: {0}", saying);
    }
}

$ gmcs Repeat.cs
$ mono Repeat.exe
Say something: is is a test
You said: This is a test

Note that it's just the keyboard echo that's a mess. The characters ARE
actually getting read. Setting TERM=dumb will cause System.ConsoleDriver to
select NullConsoleDriver instead of TermInfoDriver, which provides a workaround
assuming one isn't interested in doing cursor-based addressing in one's
console-mode application:

$ env TERM=dumb mono Repeat.exe
Say something: This is a test.
You said: This is a test.

Given the easy workaround, it's probably not super-critical, just something
annoying that needs fixing.


Reproducible: Always

Steps to Reproduce:
1.Build code shown in details above
2.Run program in a terminal window; type some input
3.Inevitably, the first character or two typed won't properly echo
Actual Results:  
First character or two typed does not properly echo.

Expected Results:  
All typed characters should echo properly.
