Re: Request: Serial Port

It would be nice is a standard serial could be added. Or at least the pins so I could plug in a serial port. That way I could interface to some micrcontroller projects without have to get a USB adapter.

Agreed, there's a lot of things that "would be nice" to see on the r-pi (and there are a lot of threads about it, including one that I will add to the read first thread right now called "What have we missed?" unfortunately size and price are major limiting factors for the r-pi :(

I do know that the alpha board has a spot for RS232 (in the form of pads) us hobbyists might be able to do some work with that?

It's not an RS-232 in the traditional sense. It's more akin to a debug console port that exposes TTL serial to something that a 3.3v FTDI Serial to USB adapter would provide to someone.

Will it be available or is it for debug purposes only ? Cause i was planning to use an old TTL->RS232 converter from an old ZiLOG dev board to talk to a netduino.

It's 3.3v, but we will be making the header available. We routinely spawn a getty on it, so you shouldn't have a problem.
