- Hardware handshake RTS/CTS
- COM port from Device Manager
- Jumper Settings - Normal operation
- Left jumper in right position (loopback data)
- Middle jumper in left position (handshake = active/ground)
- Right jumper in right position (loopback handshake)
- Type on keyboard and verify it returns data
- Verify both LEDs on the UUT light
- Jumper settings - Test Tx/Rx isolation
- Move left jumper to left position
- Type data nothing should come back
- Verify RX LED on the UUT only lights
- Move left jumper to right position
- Jumper settings - Test RTS/CTS
- Move right jumper to left position (handshake controlled by middle jumper)
- Type and characters should return
- Move middle jumper to to right position (hardware handshake off)
- Type and nothing should go through
- Move middle jumper to to left position (hardware handshake on)
- Characters that were buffered should come in at once
- Mark test coupon on rear of card
