We recently aquirred a DMR11, in order to establish a 56 kb, DDCMP Decnet link.
It is installed on an 11/780, with 16 mb memory. At the time we installed the
DMR11 the DDS circuit wasn't ready, so we are using it on a 9600 baud analog
circuit, with an rs232 interface.

The problem we are seeing is that the DMR11 is giving us extremely poor
performance; in fact, replacing the DMR11 with a DMF32 sync. port gave us
30 times greater throughput, as measured by DTSEND. I had to steal the DMF,
so just using it is not the answer. Does anyone have any insight in using
a DMR11 at this low speed. Have we goofed up the switch settings, etc? Any help
would be appreciated.
