Are you using SetCommState on the port ?
If so, are you first doing a GetCommState ? This sets up the DCB
structure to valid values

Hi all,
I m communicating to a printer device through serial port.It
is failing to open the port,but when I disable and enable the com port
in device manager,it works fine(i.e)it communicates with the printer
and reads the configuration settings of the printer).
Regards
Hari
I would be wary of using/trusting GetCommState(), lots of people seem to
have problems with this function, see other threads/newsgroups.

After CreateFile , the API's are failing,
(setcommstate,getcommstate,SetCommTimeouts).On giving
Getlasterror(),it gives error code 1 .(Incorrect function).but after
disabling and enabling com port in Device manager,all the API are
failing. :(
Regards
Hari
