Summary0000002: Carriage return treated as ^J ^J ^J in char mode
DescriptionThis is something of a compatibility/consistency problem. In LDMud 3.2.9, when using charmode (i.e. key by key input), it would call my input_to function once, and it would send a ^M (character 13). In 3.3.453 (what I am using right now), it sends three ^J characters (character 10), calling the key input function 3 times.
Additional InformationI've got a charmode test utility which I can send if it will help diagnose things, though it is a bit specific to my MUDlib. If you want to play with it, just login to, get to a command prompt, and type 'keytest'. Push buttons and see what you get (no mud clients, of course)

Here's a small program that should duplicate this (ought to be lib-independent):

void runtest( string s ) {
   string mesg;
   int i;
   mesg = "Received: ";
   for( i = 0; i < strlen(s); i++ )
      mesg += s[i] + " ";
   if( s != "\27" )
      input_to( "runtest", 2 );
   write( mesg + "\n" );

void start_test() {
   input_to( "runtest", 2 );

Hitting "Enter" twice, I get this:

^MReceived: 10
Received: 10
Received: 10
^MReceived: 10
Received: 10
Received: 10

The local echo claims it's a \r (^M), but the MUD is sending \n (^J), three times.

The driver didn't treat CR and LF as normal characters in charmode, as it should have, but instead tried to interpret them as line end. Treating them as normal data characters in charmode solved the problem.

Corrected in 3.3.467 .
