- Yes, everything seems correct. (the only difference is the DECstation has
- the flag DYNPROTO set and I can not see how to turn this off, if it is
- at all possible). Using netstat I can see that the packets are getting
- from the IBM to the DECstation but then being dropped as errors (either
- block check errors or framing errors or both). The only other variable is
- a DESPR that just the DECstation sits off of.
