Sounds to me like a protocol analyzer. Typically used to watch both sides of a conversation unobtrusively. The ones I worked with were for RS232 serial data. Very useful for debugging communications programs. The link appears to be broken though.

It's a multiprotocol analyzer for serial data. It uses RS232 for its I/O, and is vintage about late 70's to early 80's. In answer to your question as to what it's for, it was used primarily to test dedicated (point-to-point leased line) data hookups that used modems. It can also be used to test the modem itself, as it contains a FOX generator. They're extremely versatile and useful if you happen to be troubleshooting any kind of simple serial data hookup. They can generate and decode ASCII, Baudot, Selectric, and various other codes (depending on what options were installed). *********** REPLY SEPARATOR *********** On 01-Jun-04 at 08:39 Degnan Co. wrote: -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
