[hcflinux] Semi-success with a "no name" modem

When I recently found myself forced to replace a trusty old
external serial "real" modem, I thought I wanted to try and get
the plunge into the world of soundcards-with-a-phone-jack. The
first "modem" I found was a PCI card with a Conenxant chip on it.
00:0c.0 Communication controller: Conexant: Unknown device 1085 (rev 89)
(numerical, it's 14f1:1085)
And the main chip says the following:
"conexant cx06834-11 e298967-1 0248 mexico"
Googling showed that 1085 may be either HSF or HCF, while
"cx06834-11" showed up some HCF modems.
So I first tried the HSF driver, which claimed it didn't find
anything. The HCF driver, however, said
Config for modem unit 0: /dev/ttySHCF0
Device instance: 0-PCI-14f1:1085-14f1:1085
HW revision : DP Part '73' Rev 'BA' Asic ID 0x86
HW profile name: hcfpciv90
Registration ID: 3AE7-2902-5B75

while dmesg tells me
PCI: Found IRQ 11 for device 00:0c.0
ttySHCF0 at I/O 0xd400 (irq = 11) is a Conexant HCF controllerless PCI modem (PCI-14f1:1085-14f1:1085)
using minicom on /dev/ttySHCF0 and typing "ATD<number>" indeed
dials this number, and when picking up manually, I hear the
characteristic "beep... beep... beep" sounds. However, as soon
as I make any noise, the line is immediately disconnected, and
minicom shows the modem telling me BUSY.
I get the same result (dialing -> pick up -> immediate hangup
with BUSY) when a real, working modem picks the line up.
Dialing the winmodem's phone line gives no visible results, i.e.
Does anybody have an idea what might be wrong?
