Sounds like your terminal type is set incorrectly.  Specifically, it sounds
like Emacs thinks you are on a terminal that can insert characters in the
middle of the line, which the VT100 cannot do.  It is sending the "enter
insert mode" escape sequence and then sending the inserted characters, but
the emulator correctly ignores the escape sequence and the characters just
overwrite what was there.

Make sure that you set your Unix terminal type to "vt100" when you login
from the modem.
