Crossposted-To: comp.os.linux.help Subject: How to know if term is "active"? Date: 6 Sep 1994 10:41:16 -0600 I'm wondering if there exists a utility which would let me determine if an existing term connection is actually alive, and not crashed or hung, as is often the case resulting from a less than perfect phone-line. I was thinking something along the lines of a program which would output "socket is busy" or whatever. I've already written a somewhat kludgy script to allow me to do this, but it's very inefficient, and I *know* there has to be a better way. The problem is this: I can test the connection with a simple 'trsh cat testfile'. ('trsh echo ok' results in a broken pipe...) This is not a problem if the connection is alive. The problem is when the connection has dropped, since term is still running on the local machine, and when a trsh or anything term-related is sent through the socket, the command hangs. So, the kludgy part is a background process started when the 'trsh cat testfile' is executed, which checks 30 seconds later to see if the command has produced any output. Yuck! Suppose the connection *is* alive, but the remote machine just happened to be lagged during the 30 seconds... So you can see it's pretty icky. :( The whole thing is necessary since I want to be able to initialize a term connection if one doesn't already exist whenever a user tries to run a term-specific program. Hmm...I suppose the remote machine could send a character every few minutes, or an empty file, which a program could check the last mod time... So anyway, if anybody knows of a program which can quickly and accurately determine if the connection is valid, it would be greatly appreciated. Side note: Has anybody had problems with tredir in term 119? Mine won't redirect *anything*. I had no problem with term 203's tredir... But 203 just wasn't stable enough at the time... ;) Side note ii: Tin+term has given me a major headache, trying to compile the darn thing. Mosaic, ftp, telnet, irc have all gone fine with only a few minor changes. So here it is: does anyone have a binary of a working tin using the term port/socket calls? THAT would be greatly appreciated, as I have to read news on the remote machine in text mode....:( Thanks for reading/skimming/scanning...

While Intel did a port of gcc-2.4.0 to add Pentium optimizations, they did a really poor job of it, violating the front-end/back-end boundary, putting things in the wrong places, writing the code in a sloppy way: the effect is that all of their changes need to be rewritten. This is being worked on, but the FSF has a consistent answer when asked questions about when something will be ready: when it's ready. The Intel port of 2.4.0 is available in the meantime, though no one is supporting it (at Intel or FSF). -- -- Joe Buck Posting from but not speaking for Synopsys, Inc. ***** Stamp out junk e-mail spamming!

Date: 5 Sep 1994 10:48:48 +0200 I would like to know how to find the names of the colors that are defined by the XVGA16 generic driver. Is there any way of substituting colors defined by a application so it matches with my generic driver.
