im_receive_buffer_noprot
If IM_INFINITE_TIMEOUT is selected, the function will not return until the
end of message character has been received.
The term_char parameter is the end of message character needed to
terminate input from the communications port. The character is normally a
carriage return, but you can set it to any other character.
OUT Parameter: The comm_length parameter retrieves the actual number of characters
received.
The status_code parameter is one of the standard status codes defined in
Appendix A, "Status Codes."
Return Value: None.
You must install the PHIMEC.EXE protocol handler. This procedure will
Notes:
not work if linked.
The difference between this procedure and im_receive_buffer_no_wait is
that when im_receive_buffer_noprot returns from the procedure call, the
data has been read, the timeout has expired, or an error was encountered.
