When using modems of any type, quite often a failure occurs with the number 633 (connection error). And although today the use of modems, to put it mildly, is not up-to-date, nevertheless, for some systems, such a connection may be relevant (for example, when starting the modem of a mobile device in order to access the Internet from a computer).
