My 3b2/700 periodically looses one or more serial ports on an eport card. It may lose a port or two a week on any of its eports cards. At the present time, the only way I have found to clear the condition is to reboot. The symptom is that no data will move into or out of the port. I presume that I could probably "re-pump" the eport card, but I can't seem to find the appropriate command syntax. Any idea why? I have lots of ports with Hayes modems used for a dialup application moving lots of binary data. After a while, the port is simply shot: the modem won't answer, and I cannot send data to the modem either. -- Kevin Kleinfelter @ Management Science America, Inc (404) 239-2347 gatech!nanovx!msa3b!kevin

We had the same problem with the eports boards on our 3B2/500. We found that we were running release 1.1 of the eports software (which was loaded off the tape), but that we had release 1.2 on installable diskettes. When we removed 1.1 and installed 1.2, the problems pretty much went away. (We were able to use the 1.2 disks to remove the 1.1 sotware.) We still occasionally experience a hung port, probably because we running too many ports on individual boards at 9600 baud. We spread the load out across the boards; this seems to help, too. There are some fairly severe limits as to the number and speed for the ports on the ports and eports boards. You should be able to find that in the eports docs. -- Jeff Wieland wieland@ecn.purdue.edu

We had similar problems running eports 1.1 on our network, except it showed up as printers mysteriously disabling. Right now, our standard 3B2 configuration is eports 1.2 (from diskette). However, eports 1.2 is still not perfect - it has some problems with flow control when talking to various non-AT&T machines. We have had a beta 1.3 running successfully for a while on one of our test machines, and just received the official 1.3 version (although we haven't really tested it yet). You might want to contact your AT&T sales rep if you want this version. As far as pumping the board, I'm afraid I don't quite remember the syntax either (I'm at home now without access to manuals). I do know that the code to be downloaded is in /lib/pump/eports. What does /etc/pump do? -- Kevin Darcy, Asst.

After pumping, 'kill -9' all processes that have opened one of the ports on the board. -- Pim Zandbergen internet : pim@cti-software.nl CTI Software BV uucp : ..!uunet!ctisbv!pim Laan Copes van Cattenburch 70 phone : +31 70 542302 2585 GD The Hague, The Netherlands fax : +31 70 512837

Turn off all getty's (and uugetty) on any of the ports. Then I believe to reload the firmware with the pump command, you need to specify the first port on the card (ie. tty11, tty21, tty31, tty41, etc...) -Lenny -- | Lenny Tropiano ICUS Software Systems [w] +1 (516) 589-7930 | | lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 | | {ames,pacbell,decuac,hombre,talcott,sbcs}!icus!lenny attmail!icus!lenny | +------- ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752 -------+
