umm ... so the client doesnt wait for any information from the ftp server
before entering the username?
I thought that waiting for 220 was something that would be done... maybe I
am dreaming though :)
Maybe I should read some of the code sometime ;)

quite possible ... although in the 3 occasions I tested, they were all done
on the same computer with gcc, 1 failed the others didnt, the one that
failed was version 128, the ones that didnt were 129... this could be
spurious ... since I have had programs where adding a variable declaration
in file A, resulted in program stopping working due to variable B in file C
not being initialised to 0 anymore... (since I hadnt initialised it at all
in the first place ... oops)
