Applinx and DEC(HP) Alpha server with TRU64 Unix

I want to access an application developed in COBOL on a TRU64 Unix ALPHA(HP) box.This is very old system.
Please suggest if it is possible

The system is VT host.
Please check if the system uses one of Applinx supported device types.
Applinx supports the following VT device types: VT100, VT220-7 and VT220-8 in version 5.2,
In Applinx 8.0 VT is not supported (should be supported for Applinx 8.1
