This sends a CR-LF End-of-Line, but as a response to Ctrl-M. In line 
mode the telnet client reads Ctrl-J or LF when the user presses enter.
The right thing to do would be to revert this change and to add
+  else if (c == '\n' && G.charmode != CHM_ON) {
+    outbuf[j] = '\r'; /* LF -> CR LF */
+    outbuf[j++] = '\n';
+  }
