ok, this is how it should look like - there are some CARRIER / PROTOCOL /
... messages, and then the CONNECT string.

But this is very weird.  AFTER the CONNECT, there is yet another
"PROTOCOL:" message - which mgetty interprets as login name, because there
MUST NOT be any further message after CONNECT.

There could be two reasons for that:

  - the client side (caller) is echoing some messages back to the modem,
    and thus their "PROTOCOL" message is coming back to you.  Try with a
    different client modem and client software.

  - your modem is very braindead.  Try going into "minicom", waiting for
    an incoming call, send ATA, and look what happens.  There should not
    be any message after "CONNECT" (except what the user at the calling
    side is typing).

  - something very weird is going on - try different modems at both ends,
    different serial cables, different serial ports, etc.
