On a VAX3600 running Ultrix 3.1 with a Hayes Government Modem the following errors are reported on the console and by uerf occasionally after a dialin session is terminated. The rd and sd lights on the modem are full on. I looking for a better understanding of the error to help track down the cause (modem, configuration, hardware fault) as this hangs the machine until the modem is turned off. --R J Auletta rauletta@sitevax.gmu.edu dhu1, line4: recv. fifo overflow ******************************** ENTRY 2. ********************************* ----- EVENT INFORMATION ----- EVENT CLASS OPERATIONAL EVENT OS EVENT TYPE 250.

One night the system console ran through about 100 pages of paper while printing error messages before the paper jammed. The modem lights rd and sd were on constantly when we got these errors, too. We replaced the 2400 baud modem with a Telebit T2500, and we have not seen the trouble since. -- Guy Helmer work: DSU Computing Services, Business & Education Institute (605) 256-5315 play: MidIX System Support Services (605) 256-2788 dsuvax!ghelmer@cs.utexas.edu, ...!bigtex!loft386!dsuvax!ghelmer
