I want to use the program "Hyperterminal" to access my COM2 port in Win PE. So I copy these files :'hypertrm.chm', 'hypertrm.dll', 'hypertrm.exe', 'hypertrm.hlp' to "\I386\system32" folder. But when I run "hypertrm.exe" in Win PE, I got the error message "TAPI error" and cann't access the COM2 port via Hyperterminal .... So How to use Hyperterminal in WinPE? Should I add more drivers into Win PE??
