I know that this is a possible error of baud > rate but the baud rate on putty and on ecos are correct(115200). Any time the received string and expected string differ that much in length, it pretty much has to be baud rate. Have you actually verified that eCos board's baud rate is correct? By 'verify', I mean hook up an oscilloscope or logic analyzer to the eCos board's TxD line and measure the baud rate. -- Grant Edwards
