The baycom modem really doesn't have anything to do with RS232, it just
uses the RS232 port as a PIO port + timer. That's why it needs its own

A few people asked me if it is possible to drive one of those RS232

No way. For 9k6 you're polling the RX line say every 25us. That's just
not feasible
Hi,
The baycom_ser_fdx driver did not allow i/o ports = 0x1000. Now that
there are pci cards (with rs232 ports) which use for example 0xb800 this
limit should not exists.
Also, for non kernel coders find the cause of problems was challenging
so I added extra logging.

The IRQ test is also wrong for PCI systems the moment an APIC is present.
NR_IRQS is the define to use.
