Info-3b2 Digest, Number 46 Tuesday, January 3rd 1989 Today's Topics: Intermittent Ports Hanging Re: Intermittent Ports Hanging ---------------------------------------------------------------------- Subject: Intermittent Ports Hanging Date: Mon, 02 Jan 89 08:05:15 -0500 From: len@netsys.COM Has anyone experienced ports problems,primarily with cu while using either the eports or standard ports hardware? It seems that this happens at least once a week on some machines I use.. Usually using cu to access another machine at speeds of 9600 and up.. The task never terminates,and a reboot is neccessary. I have tried using a breakout box to drop cd,dtr,etc to cause the port to recycle,but nothing avails.. I am running 3.1.1 with the latest eports drivers. Enquiring minds would love to know. len@ames.arc.nasa.gov or len@netsys.com ------------------------------ From: rich@jolnet.orpk.il.us (Rich Andrews) Subject: Re: Intermittent Ports Hanging Date: Mon, 2 Jan 89 22:32:13 CST I have seen the same problem on a vax 11/750 running sys5 3.1....it seems that the tilde period sequence has to be entered SLOOOWWWLLLYYY and with some delay between the characters so that the cu does not hang out there tying up the port. Yes it does turn into a neo-zombie process from planet 3 when that happens. Kill -9 is ignored. I hate it when it does that! Eports have a unique set of problems all their own also. I know one of the hardware designers of that beastie and there are a set of circumstances that will leave the eports card in an insane mode. It seems that if a user is cating (catting?) a file and then loses the connection (drops DCD) it leaves the board in an insane mode. On the same note, I recently tried kermit on my 3b2/400 and after it tried to connect to a port, it left that port in an insane mode and I had to power down the machine. I did not try to pump the board but it is a bit scarey to have that happen that I never bothered to see if I could pump the board back to some sort of normalacy. Gee I hope all of that make some sort of sense. rich andrews ------------------------------------- To join this group or have your thoughts in the next issue, please send electronic mail to Ken Davis at the following address; {pacbell,netsys,hoptoad,well}!lamc!info-3b2-request The views expressed in Info-3b2 Digest are those of the individual authors only. ********************* End of Info-3b2 Digest *********************
