>Description:
The Moxa Technologies CP-104EL PCI Express 4 port Serial card
would appear to use the same MOXA controller as their PCI cards
with the addition of a PCI Express to PCI bridge chip:
It uses a different device id to the PCI cards and is not recongnised
by the puc device without adding support.
After adding support gives:

Accessing /dev/cuau0-3 with a modem attached appears to work fine.
>How-To-Repeat:
Install CP-104EL card.
Add puc device to kernel config, build kernel, install kernel, reboot.

"Moxa Technologies, Smartio CP-104EL/PCIe",
DEFAULT_RCLK * 8,
PUC_PORT_4S, 0x18, 0, 8,
},
