RE: custom serial driver
Yes, that is true. You can't send data byte by byte if dma
is enabled for the serial port.

Subject: custom serial driver
I'm elaborating with a serial port on Etrax and has a custom driver
If enabling DMA, it seems I can't send data in old fashioned polled
mode (byte by byte). Is this true, can't the two coexist?
