Da un giorno all'altro, dopo aver cambiato alimentatore (????) non mi funziona piu il modem esterno seriale 56k...devo dire che non avevo avuto particolari problemi ad usarlo con linux fino a che ha smesso di funzionare.
Sto pensando che forse è un problema della porta seriale...le ho provate veramente di tutte :
pppconfig mi trova /dev/ttyS0 ma quando faccio pon xxx non si accendono nemmeno le luci
kppp dice "unable to open modem"

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

If you still have problems, send mail to wvdial-list@lists.nit.ca.
Sarà un problema della porta seriale ?

googlando un po ho trovato che :
LSR is the name of a hardware register. It's claimed that this means there is no serial port at the specified address.
!! ma come !! allora sono andato a vedere nel bios, ho una mobo asus k8v-x e alla voce serial mi fa scegliere tra:
3f8: irq 4
2f8: irq 3
3e8: irq 4
2e8: irq 3
le ho provate tutte ma non cambia nulla con i vari wvdialconf,kppp,minicom e pppconf.
guardando i log del kernel ho visto che :
# cat /var/log/kern.log |grep ttyS
...
Quando andava :
Nov 29 11:04:08 catorcio kernel: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
Nov 30 14:14:46 catorcio kernel: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

Oggi:

Apr 21 19:51:21 catorcio kernel: ttyS0: LSR safety check engaged!
allora mi sono deciso a smanettare con setserial...con il comando setserial /dev/ttyS0 -v autoconfig non cambia nulla :D
ecco cosa dice setserial:
# setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
# setserial /dev/ttyS1
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
# setserial /dev/ttyS2
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
# setserial /dev/ttyS3
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
# setserial /dev/ttyS4
/dev/ttyS4, UART: unknown, Port: 0x01a0, IRQ: 2, Flags: Fourport
[UPDATE]
ho provato anche con
"dpkg-reconfigure setserial" e a disabilitare il file di configurazione di setserial scegliendo il metodo "kernel" ma non cambia niente..
spero che qualcuno riesca ad aiutarmi, come avete visto le ho provate di tutte :cry: non ce la faccio a stare senza linux !!!!!! :help: :help:
