"M3110 DRCSA U Protocol assist #1
w/special character check
and CRC (DEC/DLC/DRCSA)"
"M3111 DRCSA U Protocol assist #2 w/special character check
and CRC (DEC/DLC/DRCSA)"
No clear idea about those two...
I checked with a co-worker (who did service PDP-11's)
He thinks it may have been used as X.25 router/ lineinterface.
Usually there is also a M3112 card (boot/terminator for DECSA)
