I'm very new to the UNIX system, having used MS-DOS (like the rest of the 
world) for ages.  Unfortunately, the host system that I call for Internet 
Access via my modem uses this system, and I'm having a lot of 
difficulty with a few things on the operating system.  (In short, it's 
kinda like being thrown in the deep end of a pool and being told to swim 
when you've never taken a swimming lesson in your life.)  I really just 
need enough to get by, and any help you can give me with the problems 
below would be very much appreciated.  One of the problems that I'm 
having was posted previously by user, but wasn't answered.

I've managed to solve quite a bit by trial and error, but here are the
few headaches...er...problems that are still bugging me:

1.  FTP downloads.  I have a personal shell account on this host system.
    I figured out how to transfer a file from a remote FTP system to 
    the UNIX system I'm calling by modem, but I do not have the slightest
    idea how to transfer the file from the host system to my PC at home.
    If you could give me a step by step guide to this, (the "for dummies"
    version in English), I'd appreciate it.  (That is, providing it's 
    possible.)

2.  TIN program to USENET.   How do I write a post and NOT save it to 
    disk, yet have the entire content of the buffer transferred to 
    the USNET forum?  I tried not saving a document, (as you can 
    probably tell by the blank post previously), and lost it when 
    I tried to post.

3.  Backspace Hell.  When I log onto this HOST UNIX system, I 
    immediately have a problem with the backspace key.  It does
    not destruct characters in its usual manner.  Instead, it 
    gives me a ^H.  This is a royal headache.  I figured out 
    that if I type STTY erase and then hit the backspace key,
    I get a destructive backspace key, however, I have to do 
    this everytime I log on.  Is there anyway to save this 
    preference, so that I don't have to go through this all
    the time?

4.  INTERNET GIF FILES to UNIX.  How do I transfer GIF files
    that are in BINARY code to the unix system and then to my
    PC?  Usually these are posted on a USENET forum, but I'm
    not sure of the process of doing it, and the FAQ deal is 
    hard to locate.


Again, any help you can give me would be greatly appreciated.

Thanks in advance for your time.
