This is called DMA mode of the UART chip. With this you can configure to get the interrupt after certian number of bytes are received instead of single byte interrupt. hope this helps. /Ravi -----Original Message----- From: Vinayak P Risbud [mailto:vinayak@multitech.co.in] Sent: Tuesday, July 16, 2002 7:08 PM To: Ecos-Discuss Subject: [ECOS] serial port ARM e7t problem Hi, I have set, ARM e7t port to Baud 38400, I think, the board interrupts the ARM core for every character read. (instead of for a bunch of characters) And because of this, I am loosing some characters, Can anyone give me, any solution for this problem ? ~ Vinayak ~ Vinayak --=20 Before posting, please read the FAQ: http://sources.redhat.com/fom/ecos and search the list archive: http://sources.redhat.com/ml/ecos-discuss -- Before posting, please read the FAQ: http://sources.redhat.com/fom/ecos and search the list archive: http://sources.redhat.com/ml/ecos-discuss
