[BusyBox] Make udhcpc request IP address in different port ?

[Steven Shiau]

Hi,
I did not express well in the previous post. so please allow me to ask 
again:
I already configured my dhcp server listen in port 1067. How can I make 
my client to run udhcpc to request IP address in different port (say 
1001, not 67) ?
If this function is not implemented in the version (v0.9.9-pre), is that 
possible in the next version it will have ?
Thanks in advance.
