PC Card Adapter Flow
Psion --> rs232 --> max3243cai --> ttl --> Siemens CAB C165 LF --> PCMCIA
Notes
- The C165 does not have hardware flow control pins (just rx/tx) so must bit-bang the flow control.
- The cable has 10 pins and is socketed - looks like molex
- Cable wires:
- Black (sheathed)
- Blue
- Brown
- Red
- White
- Yellow
- Black
- Green
- Orange
- Red/White
- Looks like there are 2 extra wires in the cable that aren't used and cut down.
ToDo
- Identify wires
- First will just continuity test against the max3243
