[linux] problem s modemom

[Mario]

Ako rozchodiť modem Sysgration ?

Sú 2 možnosti:

1. nakonfigurovať podľa dokumentácie pomocou prepojek na modeme:
      -vypnúť PnP
      -nastaviť port,adresu,IRQ - pozor na konflikt ak  
                                  mate myš na COM1 nemôžete použiť COM3
                                  COM2 nemôžete použiť COM4
      -symlink /dev/modem nastaviť  /dev/cua2 ak mate nastavení COM3
                                    /dev/cua3 ak mate nastavení COM4
				    
				    
2. pomocou isapnp				    
     - treba mať nainštalovaný balík - isapnptools
     - nastavíme v isapnp.conf port,adresu,IRQ treba dať pozor na konflikty
     - v /etc/rc.d/rc.sysinit doplníme riadky podľa konfigurácie
       napríklad pre COM4 IRQ3:

# set up pnp 
if [ -x /sbin/isapnp -a -f /etc/isapnp.conf ]; then
    if [ -n "$PNP" ]; then
	action "Setting up ISA PNP devices" /sbin/isapnp /etc/isapnp.conf
        setserial /dev/cua3 irq 3 autoconfig
        setserial /dev/cua3 spd_vhi
        setserial /dev/cua3
        stty -echo < /dev/cua3
    else
	action "Skipping ISA PNP configuration at users request" /bin/true
    fi
fi

     -nastaviť symlink /dev/modem 
     

   - príklad  /etc/isapnp.conf pre COM4 IRQ3:
