I've seen this issue before but haven't been solved yet.

When I send an AT Command to a GSM modem and waiting for a small reply (like "OK") everything is fine.
But when I expect a longer reply from the modem (like 50 characters) I cannot receive all the string.

I have tried with many types of circular buffers.
I have realised that its a matter of IRQ because its not possible to ensure the time of its arrival.

Can you propose a way to wait for the whole string to arrive and then proceed with the program flow ?

Thanks a lot.

(I use LPC1115)
