Aharpo.442 net.general utzoo!decvax!duke!harpo!jerry Mon Mar 22 11:13:42 1982 mpx Help wanted I am trying to use mpx files under 4.1bsd for the first time, and can't seem to get them going. I get channels connected to to processes and a few characters through, but then, characters seem to get lost (these are characters being sent from the "normal" to the mpx side). Apparently, when some internal buffers get full UNIX is just throwing stuff away, instead of suspending the process doing the write. I would appreciate any ideas, or a call from somebody with experience in this area. Jerry Schwarz harpo!jerry BTL, Whippany 201-386-6212 P.S. I would have sent this to unix-wizards if I knew the proper way to do that since Berkeley closed down.
