I'm no Unix or C expert, but I suspect that it does this; the code
includes the following, which seems to do a close and re-open :-


			/*
			 * XXX EIO may occur: port hung up by other process!
			 * Reopen it - danger: reopening failing continously
			 */
			close(modem);
			modem = modem_open(modem_file, TRUE);
			continue;
		}
