This sounds something like the problem I'm having. I use
Minicom's runscript to connect with an ISP. The ISP has one or
several modems that act up occasionally -- locking carrier but
not doing anything else or not answering at all. Runscript seems
to have forgotten how to hang up now. Here's the problem area:

HANGUP:
    set h 0
HANGUP2:
    inc h
    print "\n..hanging up"
    send "+++\c"      <== seems to get caught up here
    sleep 3
    send "ATH"

    expect {
        "OK"    goto DIAL
        timeout 5
    }
    if h < 2 goto HANGUP2
    goto ERROREXIT

DIAL:
    send "ATDT5555555"
    expect {

This didn't happen with the bo runscript, so I compiled that
version against libc6. Back to the same old problem; wouldn't
hang up. So now I'm using the libc5 runscript. Works fine. But
I'd like to get rid of it as it's the only program on my system
that requires libc5.
