[comp.os.vms] Ultrix <--> VMS Communication

5401025@FSU.BITNET (06/02/88)

Thanks to all who replied. I have received several replies and most of them
suggest to look at implementation of TELL. What i've found out in the meantime
is that the READ/WRITE on both sides helps. In other words after Ultrix side
writes, VMS needs to read and subsequently write back (even some dummy string)
which Ultrix reads and the cycle repeats till the end. I found that out by
accident and out of desperation. What is interesting though is that the write
from the VMS side does not need to immediately follow the read in order for
read to succeed. I guess the key is that the Ultrix side now waits with its
read before issuing another write or closing the socket and thus VMS can keep
up and not receive the EOF on some read.
