Organization: Pyramid Technology Corporation We have just begun using a Shiva Telebridge with a Telebit T1500 modem. The application is mostly NCSA Telenet from people's homes. The question is one of the communication protocol that best serves the user. It appears that V.42 with LAP works great for things like FTP, but between the compression and the protocol itself (I'm told that it is actually a half-duplex protocol with line turnaround -- is this true?), character echo time for the shell is terrible. In fact, a ping to the Mac (with MacTCP) from one of the unix boxes takes 350ms for the round trip! Interactive response time seems to be significantly worse then that. V.32 with MNP (or without MNP!) may be a better choice -- but I hate to experiment and end up with a sub-optimal solution. I would like to optimize for the smoothness of response for interactive shell/vi users. Does anyone know the 'best' way to hook up all of these gizmos? Please respond via mail -- and I'll summarize the responses. Thank you, Bruce Beare bjb@pyramid
