No obvious clues there. In fact, things were stranger than I indicated
previously. After changing the permissions in /dev/ttyS0 I was unable to
log on at all as user; I kept getting messages about
/etc/ppp/peers/myprovider not existing! (Though I could still log on a
root). After two reboots (not one) everything started working again
including minicom. I have no idea how all this happened, nor do I
understand why /dev/ttyS0 had originally got incorrect permissions while
/dev/ttyS1, etc, were correct.
Anyway, all's well that ends well.
