DCOM (Data COMms) card
For this card I took the core comms code from one of existing terminals
and added a PC interface task. I then produced the interface code for
the PC applications to use. The code in the card is in 6809 assembler
and uses a multitasking kernel. The PC code is in Modula II. The DCOM card is also covered in the hardware section.
