SuSE Linux: All versions
"How can really be adjusted a Linux device for a serial interface (e.g. /dev/ttyS1) to a not standard I/O address (e.g. 2E8hex)?"
For this purpose serves the programme setserial
(see also
man setserial). In the case mentioned, setserial ttyS1 port 0x2E8
irq 3
must be called.
