GetCommError

int GetCommError(idComDev, lpStat)

int idComDev; /* Communication device ID */

COMSTAT FAR *lpStat; /* Address of the device status buffer */

The GetCommError function is used to acquire the last error value and current status of the specified

device. If a communication error occurs, Windows will lock the communication port until the

The OpenComm function returns this value.
