Just what I thought. But how do you set up a large typeahead buffer for a device which is created on an ad hoc basis. I've tried setting up an applications port on the systems, but it doesn't seem to work. What I really need is an interactive port. But that's not an option in LATCP. Anyy other ideas? Thanks, R. Kevin Oberman Lawrence Livermore Nat'l Lab arpa: oberman@lll-icdc.arpa (415) 422-6955 A FEW. I POSTED AN ANSWER TO THIS A FEW DAYS AGO BUT I DON'T THINK MY RESPONSE GOT MAILED PROPERLY. CHECK OUT THE SOFTWARE AT THE OTHER END, NAMELY THE NBI. I SETUP SOME NBI MACHINES A FEW MONTHS AGO AND I SEEM TO REMEMBER THAT THE NBI HAS AN OPTION IN THE COMM SETUP SOFTWARE THAT ALLOWS YOU TO INSERT A TIME DELAY AT THE END OF EACH LINE IF YOU PLAY AROUND WITH THIS PARAMETER YOU WILL EVENTUALLY FIND A VALUE THAT PREVENTS THE BUFFER OVERFLOW PROBLEM. IF THIS FAILS TRY SLOWING DOWN THE BAUD RATE TO 1200 BAUD. MOST WP'S HAVE A LOOKUP TABLE THAT ALLOWS THE INCOMING ASCII TO BE CONVERTED TO WHATEVER CHARACTERS YOU CHOSE. THIS ALLOWS THE MACHINE TO BE MORE FLEXIBLE, BUT ALSO SLOWS DOWN THE COMM QUITE A BIT BECAUSE THE WP'S MICRO HAS TO DO THE CONVERSION BEFORE THE CHARACTER IS SENT FROM THE KEYBOARD OR TYPED ON THE SCREEN.
