i use redhat 3.0.3 with kernel 2.0.30. how to set modem in com3 IRQ 5 in linux? usually com3 is IRQ4 but i want it to 5(i set the jumper 5). the device is cua2 which i believe right.
the reason is the my 33.6 modem is extremely slow(few characters per minute) in linux so terminal software(like minicom) and PPPd don't work. someone suggest it may be the wrong IRQ of modem in linux.
