repost: serial problems..please help

["jdls" <jdls@apu.edu>]

Hi,

I don't know how to fix this.... but my computer doesn't seem to
have any serial ports.. I have read in the man pages that using
setserial without any arguments should display the serial ports that
I have but it gives me nothing..using a specific command like
setserial /dev/ttyS0 tells me that there is no such device?
ls -al /dev/ttyS* tells me that the files exists..

crw-rw----    1 root     dialout    4,  64 Jul  5 23:14 /dev/ttyS0
crw-rw----    1 root     dialout    4,  65 Jul  5 23:14 /dev/ttyS1
crw-rw----    1 root     dialout    4,  66 Jul  5 23:14 /dev/ttyS2
crw-rw----    1 root     dialout    4,  67 Jul  5 23:14 /dev/ttyS3

I have tried editing serial.conf, removing autosave, etc but still
nothing.. my serial ports cannot be seen or something... I have ran
out of ideas.. searching the internet regarding this matter has netted me
zero...

Someone please help and explain to me what had happened pls...

how can I use setserial command when I don't even have any serial ports..:(
