The parallel port kernel driver doesn't use the interrupt by default, it uses polling. (It even says so in the boot messages, at least with my kernel.) [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- On Sun, 11 Jan 1998, Dan Hugo wrote: ttyS1 - PalmPilot (or whatever it's

Re: Interrupts and serial ports

So I have taken every port to it's own interupt. But my question is: Why can I share interupt with parallel ports? I have lp1 and lp3 on the same interupt, and printing and the access to my Zip drive works fine! Chances are that, under Linux, lp1 is not really using an interrupt. The

Interrupts and serial ports

I have a SIIG serial port ISA card so I can add on two more serial ports. I was looking through /etc/rc.boot/0setserial to see how everything is configured, and I noticed that in the manual configuration section, it attempts to setup the COM1/3 and COM2/4 ports to irq's 4 and 3, respectively

of your serial ports, for all applications - getty, mgetty, kermit, minicom etc. If you are using mgetty then you do not need to use uugetty - mgetty can do everything the getty_ps/uugetty can do and a whole lot more. Also, on another subject, is there any way network audio system can co-exist
