I read somewhere, you could change the speed of the serial port?

Frank

The serial port on the car player works at 115200 bps when it's using the AC adapter (home power). When it is plugged into the car docking sled (car power), the serial port works at 4800 bps for compatibility with certain other in-car devices equipped with serial ports.

Unless you are doing something special with the serial port in a car installation, there is no need to change its speed. For what reason did you want to change the serial port speed?

I thought i had seen (in some thread) about a higher a/c home
port speed above 115200 bps.

Oh, right. The car player's serial port could, in theory, go up to 23400 bps...

The problem is that it's a pain to get that working because most PC's don't support that speed on their serial ports, and Windows simply won't go that fast even if the serial port itself can handle it. All of these things can be worked around, but the work arounds are generally a pain in the rear.

And after all of that, why would you WANT to anyway? Anything you'd be doing that required any speed can be done much faster and with a lot less troube simply by using USB or ethernet.

Perhaps this is in a faq somewhere but i haven't found any info on it yet...

I've got a straight through cable on the sled to my laptop. Laptop is at 4800 bps ... I get garbage from the player except for a little bit talking about ":4800 logging disabled" ... i can control the player by issuing character commands, so something is working right ... I just can't get a real shell prompt going.

Also, it seems there's some confusion elsewhere ... when I plug in a GPS device to the sled, do I still use a straight through, or do I then need a null modem?
