Hi,

I had created a CLASS using MSCOMM for use to interface with some
secure device. One of the device function will responsed with '*'
when user enter their pin number. How do I return '*' to my application
to display the '*' on my application screen like callback function
in VB.

In addition, the return result of '*' is temporarily, after which, it
will change to a message format that I must strictly followed, but
MSCOMM after reading, will remove the input buffer, how do I restore
back the input buffer of the data that I just read ?

Please advise, thank you
