Granted he may not be able to break out of it, so no security risk. What a pain for that user though. He has to busy out your clocal'ed port and dial again. I don't know about the rest of you, but I'm getting tired of this discussion anyway. FLAME ON Also, my opinion (unsolicited) on the subject of tying up dial-up ports with idle terminals is that this is, at best, a rude thing to do. Many systems operate with fewer ports than they might otherwise need, because the depend on only people doing real work to be using the system during busy hours. No, I'm not a sys admin, but the systems I deal with at work are administered by a pretty fair group of people. If there really aren't enough ports consistently, and those are actually being _used_, then they'll find a way to add more. But never before trying to reduce the number of logins not doing real work. Please, be considerate of other users. Running this type of program is just not fair play unless you have unlimited dcom resources or local access. As you can see from my ORGANIZATION, I do know that data lines cost $$. FLAME OFF Only I am (sometimes) responsible for my opinions. -- Robert Cohen San Francisco, California {ihnp4,dual,qantel}!ptsfa!rhc

Actually, by far the nicest use of DTR ignore is that you can put a process in background and LOGOFF freeing up a terminal while still getting your job done.. -- Myke Reynolds Office of Telecommunications and Networking Georgia Insitute of Technology, Atlanta Georgia, 30332 ...!{akgua,allegra,amd,hplabs,ihnp4,seismo,ut-ngp}!gatech!gitpyr!myke Where we are going and from whence we came are completly unknown to us... and personaly, I have no idea where I am now.
