I'm also having this problem with tftp... when I run it, the first command is processed normally but then anything else I enter get me a '?Invalid command' response. Ctrl-C doesn't even work (but Ctrl-D will kill it). If I run 'tftp' and then just enter a blank line, I get 'NULL pointer access (probably)' and the program crashes. I'm using the 2008R1.5-RC3 distribution of uClinux. 'tftp 192.168.1.5 file' works, but I think it's doing the transfers in ASCII mode.
I wonder if there's something strange with the I/O on my system... I also have a problem with 'more'... when it pauses after each page, I have to enter space + Enter to get to the next page (not just space like it should be). My busybox is 1.4.1.
