I don't have DECservers, so I don't know whether the controller is DMS or not. But I guess that they are. Irregardless, it is your responsibility to set terminal lines to DMA or NODMA using SET TERMINAL/PERMANENT/DMA or SET TERMINAL/PERMANENT/NODMA, or by setting bit 6 of parameter TTY_DEFCHAR2. Specifically, bit 6 (HEX 40) of TTY_DEFCHAR2 specifies the default setting of DMA on all terminal lines. I believe you set the bit if your controllers are DMA, and clear it if they are not. Then you don't have to perform SET TERMINAL for the lines unless you have mixed DMA and NODMA terminal controllers, in which case you have to do it for the ones that don't match your default in TTY_DEFCHAR2. Please let me know if this works for you, or if you have problems. The SYSGEN manual says that the DMA bit has no effect, but this is how we set up our systems, some of which have mixed DMF-32s and DZ-11s.
