Problem in AT commands for FTP

Hi
I m trying to upload a sample .txt file to an FTP server. It is taking too long to upload an 11 bytes file. No error, still i m unable to upload because of the time.

Also, what will be the format of "AT+FTPPUTPATH= " if i have a file in my D: drive.

AT+SAPBR=3,1,"CONTYPE","GPRS"

OK
AT+SAPBR=3,1,"APN","ufone.internet"

OK
AT+SAPBR=1,1

OK
AT+FTPCID=1

OK
AT+FTPTYPE="A"

OK
AT+FTPSERV="amna.bugs3.com"

OK
AT+FTPUN="xxx"

OK
AT+FTPPW="xxx"

OK
AT+FTPPUTNAME="upload.txt"

OK
AT+FTPPUTPATH="D:"

OK
AT+FTPPUT=1

OK

+FTPPUT:1,1,1360
AT+FTPPUT=2,10

+FTPPUT:2,10

Nothing appeaed after this.
How much time i should wait for AT+FTPPUT=2,10 to respond with 'OK'.
