My boss is ready to buy the HP-4953A. But I am uncomfortable about buying the first one we look at. Can anyone suggest any other analyzers comparable to the 4953A that we should try? We require at least X.25 HDLC, BSC, SNA and Sync/Async. We need to be able to write monitor/simulate programs (the menu system of the 4953A gets in the way here), be able to monitor timing, lead changes and be able to dump monitored data to tape. We like the ability of the 4953A to control a slave version of itself in the field (you can upload/download programs and monitored data by connecting the two with modems). I would really like to see one that can monitor a conversation and then play back say, only the DCE's half (a cheap, quicky host emulator) with timing and lead changes intact. I don't think the 4953A can do that. Thanks for your help... Michael Thompson {ucbvax,decwrl}!dual!vecpyr!altos86!mickey {ucbvax,decwrl}!dual!vecpyr!altos86!illogica!mickey
