Same thing happens with my system:

# Serial driver version 5.05c (2001-07-08) with MANY_PORTS SHARE_IRQ
# SERIAL_PCI ISAPNP enabled
# ttyS00 at 0x03f8 (irq = 4) is a 16550A
# ttyS01 at 0x02f8 (irq = 3) is a 16550A
# Redundant entry in serial pci_table.  Please send the output of
# lspci -vv, this message (12b9,1008,12b9,00aa)
# and the manufacturer and name of serial board or modem board
# to serial-pci-info@lists.sourceforge.net.
# ttyS04 at port 0x7fe0 (irq = 10) is a 16550A

Modem still works fine.

Since the grandparent poster has the same modem as mine, and my modem
does not want to dial out by echoing that command to ttyS4, I would
assume that it's the wrong way to debug the modem.

Btw, if his dmesg log is correct, its ttyS4 he should be checking, not
ttyS3, unless I am misunderstanding something.

To debug, I would try these steps:

1) `wvdialconf /etc/wvdial.conf.test`
2) Assuming you get the line "Found a modem on /dev/ttyS4" then
continue, else post another message to debian user.
3) edit /etc/wvdial.conf.test and add in a null phone number (5551234)
and uncomment the phone number, username, and password lines.
4) `wvdial --config /etc/wvdial.conf.test`
5) If you hear it dial, congrats, your modem is working.  Try putting in
your real phone number, username, and password.  Then redo step #4.
