OK Sometimes a device wants to send information (in this case echoing your commands and OKs) to the CPU. The obvious approach is to repeatedly poll the device, but that could be problematic, say if you wanted to use your CPU for anything else 8-) Since most people do have other jobs in mind, computers use interrupts - little "Oi!" messages that devices can send to the CPU. You are observing a delay because the interrupt mechanism is not working - consequentially, the CPU doesn't receive any waiting bytes until it talks to the device to send the next char. >... >sio3: configured irq 9 not in bitmap of probed irqs 0 Et voila - the CPU is listening on one IRQ and the modem is sending stuff to another. >sio3 at 0x2e8-0x2ef irq 9 on isa >... > >Is that ok? No. Your modem is not on IRQ 9. Find out what it is on, boot -c and adjust the sio3 IRQ setting accordingly.
