AFAIK it should all be done in one line:

# setserial /dev/ttyS4 irq 22 port 0xdc00 uart 16550a ^fourport

(irq and port come from *pci output, uart 16550a because that's right
for a hardware PCI modem.)

Sorry, I forgot about the ^fourport -- I had to do that for it to work
under similar conditions  (similar but different -- similar enough, I
hope).
