Need help sending AT string to modem

Hi folks,

I am hoping someone might know a solution to this little problem I want to
solve.
I would like to setup a batch file to send a text file with a AT command
string to the modem.
I already tested the AT string under XP's HyperTerm at it works, but there
doesn't seem a
way to invoke it automatically and send a ascii file with the AT command
string from the command line and then exit.
I need for this string to be sent to the modem at a scheduled time
automatically by the PC.

In the old days I could simplify put this into a batch file and it would
work. It was simple, didn't require a terminal emulation
program, but this method no longer seems to works under Win XP.

------------------------------------------------------
Echo Sending AT string
copy dialupstring.txt com3:
------------------------------------------------------

or

------------------------------------------------------
Echo Sending AT string
type dialupstring.txt > com3:
------------------------------------------------------

How can I do the equivalent today under XP?
I would appreciate your help.
