Lpc2000

Dont forget that part of the windows API allows you to extend the size of the uart buffers.
They are 4096 by default I think, but I always stretch them out to about 65K and life gets easier.

For large transfers I will typicaly send about 4k then wait for a single ack character
from the PC. You don't loose much speed and you know that the data gets there.

Hi,
I Linux-2.16 PC to collect the data sent by the LPC 2138. The 8KB data
said in the previous mail is splitted in to 128 bytes of chunks and
then transferred from LPC. If the delay is inserted between the
chunks, it is working without any problem. If delay is removed then
the PC is loosing the data.
