posted May 28, 2004 10:36 AM Does the VT terminal emulation support the KAM commands (CSI 2h, CSI 2l) for locking and unlocking the user's keyboard? I am working on adding some "host command" support to the VT emulator we wrote around the Dart VT controls, and everything works great except for situations where we need to get an answer back from the PC VT application on the UNIX host server. In those cases, the user can be typing and generating keystrokes that we don't want to get in our data transmissions (sent using the Telnet.Send method). Using KAM, we should theoretically be able to lock the user's keyboard, and then do our host command to get data from PC-land, then unlock the user's keyboard. |

posted May 28, 2004 4:07 PM Hi, I think you would have to handle that in your app, instead of sending the sequence to the server. You have control over when Send is called, so you can just not call it when you don't want data sent (for example by using a boolean conditional). -ken |

posted August 25, 2004 10:24 AM I guess I was asking, because I want to be able to control this from the SERVER. Thus, I can guarentee that when the server says "stop talking to me for a bit", the client would just handle it, and buffer the keystrokes until the SERVER unlocks it. |
