Hello!!
I am trying to send and receive some data using COMM(communications ).
I have got the handle to COM port(COM port1) by the use of
lineGetID() ( using VARSTRING datastructure).
I have only modified the timeout value
(commtimeouts.ReadIntervalTimeout = 3000; and set the others to
zero)…
When I transmit the data from the client it gives error in the client
saying ERROR_ALREADY_EXISTS (0x000000b7)… When I try to open the COM
port by using CreateFile() it gives error “Access Denied”.
Could you please advise what could be the problem…
