Summary: A cheap IBM worked! Is it the Mac's software? Message-ID: <451@mace.cc.purdue.edu> Date: 16 Aug 88 17:26:33 GMT Reply-To: ajq@mace.cc.purdue.edu (John O'Malley) Organization: Personal Computing Learning Resource Center, Purdue University Lines: 30 I know that terminal programs were discussed at length some months ago, but maybe this is a different enough situation to warrant a new discussion. We've got a Mac SE and a Mac II hooked up to our Unix- and CMS-based mainframes via an AT&T Integrated Services Network (ISN) line. The setup runs perfectly at 9600 baud using MacKermit 0.9(40) (favorite software) as well as MacTerminal 2.2 and Red Ryder 9.4. When we attempted to bounce the ISN box up to 19200 baud, we found that none of the software worked. About every 1 out of 3 characters typed in MacKermit and MacTerminal yield garbage. I couldn't even get past the password prompt at login! Red Ryder 9.4 doesn't have a 19.2Kbaud option, but I suspect RR 10.3 does. Do MacKermit and MacTerminal have reputations for running at 19.2K with any degree of reliability? Is better software available that does long-packet Kermit protocol transfers, reliable vt100 emulation, and 19.2Kbaud speed? One of my coworkers (an IBM-type person) had a good laugh when we tested our Mac's ISN line with a lowly IBM Convertible running Kermit-MS at 19.2K, and it worked perfectly ... seeming to prove the problem is on the Mac's end. Any ideas? Seeing an $800 IBM triumphantly beat a $5000 Mac II wasn't pleasant!! Please post responses; seeing some discussion would be helpful.
