ftp inconsistency ?

[Rex Fowler]

We have 3 microvax 3800's running Ultrix 3.1, let's call them A, B, And C.
I am able to successfully use A and B to ftp data back and forth.  
There are 4 combinations, all of which work fine

1) A get from B
2) A put to B
3) B get from A
4) B put to A

All 3 mvaxes are set up almost identical.  The only difference is that
C is approx 300 miles away on a 56kbps line.  Telnet's to C are successful, 
ftp's from A or B to other non-microvax machines at the same location as C 
are also successful.

I can use C ONLY IF the data being transferred is less than or equal
to 1023 bytes.  If I try to move a >= 1024 byte file, the connection hangs 
and won't let go.

Any ideas of what could be wrong or where I could look?

Thanks
