Sorry for the repost - I forgot the [EE]. Does anyone have any info on this testing device? It seems to be a comm's sniffer and terminal device. It has a small green CRT display which displays twoletter mnemonics and/or ascii characters. It also has interchangable (ROM?) devices with labels like: "STD Package" "BISYNC PKG, MNTR-PGMS" "BISYNC PKG, 3270 EMU" "PRINTER PROM" "ECP PROM LEVEL 1" I can't figure out the menus enough to try feeding it some RS-232. - Bri -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
