Re: Communicating through a GBA's link port
One question: How does the GBA know what to do with that? Last I checked, you couldn't exactly program cartridge systems yourself.
To answer your question: You would swap Rx (2) and Tx (3). There is also 7 and 8, which are RTS (Request To Send) and CTS (Clear To Send) respectively. Since you're essentially translating the circuit from DCE (Data Carrier Equipment) to DTE (Data Terminal Equipment), One would think that you could just swap RTS and CTS, but that also changes the meaning of them slightly. You could also just short the RTS/CTS pins on both ends; that is, short 7 to 8 on the DB-9 and 4 to 5 (include the resistor on the GBA end.) Of course, I don't think any of the handshaking lines (RTS/CTS and DTR/DSR) are used by the loader. Can anyone more experienced shed some light? |
