Then your software must also implement correct and complete terminal
emulation for the type you request.

Terminals aren't so simple, and a pty channel will be running a shell
intended for communication with humans and not with a program such as
yours.
It is extremely fragile and error-prone to try to automate anything
around an interactive shell. Use a dedicated server-side process and
protocol instead.

Can you verify that this happens also by modifying the example/ssh2.c
program in the libssh2 source tree?

When you execute "manually" the terminal emulation code path is
*significantly* different, that can not be compared with raw write to
a pty.

For a reliable solution you need to have a special program (either
custom-made or a standard one but one which is made to explicitly
support automation) running on the server side, and communicate with
that software using a custom or a standard protocol, also one that is
made for automation of the tasks and actions that you want to automate.
