Date: Sun 31-May-1989 01:24:51 From: Unknown Subject: modem communication problem the following problem has been giving ne headaches since i have ny NeXT. i am using a modem to connect to a JPL computer. the modem there has a security system installed that asks you for your userid and password before it authorizes you to access a communication server from which you can finally log in onto the computer you want. i used to do this with my mac 2 and the modem set on the same typical parameters: 8 bits characters, 1 stop bit, no parity, and everything worked fine. however, since i got the NeXT, i manage to access the communication server, which means that the userid and password i type (not echoed on the screen in the transcript below) are recognized and understood. i then try to type "c[space bar]" which should be extended to connect by the system, but it does not want to recognize my space bar. it does not understand my return characters either, and i have to disconnect by entering my tip escape sequence "~." i had a friend who also has a NeXT but another modem trying to dial in but he encountered the same problem. on the other hand, i have no problem whatsoever in connecting to the caltech [/nication server and from there to a caltech computer. i am hoping that someone out there might have experienced the same kind of problem in connecting to his/her local system and would be able to give me some clue on how i should try to solve this problem. it would be easier if i could tell some communication wizard my userid and password so that he can try for himself and diagnose the problem but i am not authorized to do so on the network of course. i include a transcript illustrating what happens when i try to connect (the problem occurs with both terminal and shell) and a copy of my /etc/remote file. if you have any idea , i would surely appreciate receiving your e.mail and would call you if you give me a phone number. thank you in advance.
