Ovaj dokument opisuje kako se spojiti na Internet s Option Combo WLAN/GPRS/EDGE na Suse linuxu. Na neciju zalost ovaj tekst se ne bavi WLANom ove kartice (više o kako pokrenuti WLAN). Puno informacija veznaih o Linuxu i raznim (UMTS, EDGE, GPRS) PCMCIA karticama mozete naci na PHARscape. Tako ako zapnete mozete tamo naci malo detaljnije stvari. Ovo je sve istestirano na kartici koju prodaje vip.

Ovako kada gurnete ovu karticu u PCMCIA utor naredba dmesg vam bi trebala vratiti nesto kao

ACPI: PCI Interrupt 0000:02:00.1[A] -> Link [LNK5] -> GSI 11 (level, low) -> IRQ 11
ttyS6 at I/O 0x3000 (irq = 11) is a 16550A

Tu je vazno zapamptiti “ttyS6”. To je seriski port koji je stvoren za komunikaciju s karticom. U vasem slucaju to moze biti neki drugi port (npr ttyS2). Informaciju na kojem je portu vasa kartica trebalo bi zapamtiti.

Inace PCMCIA kartice se mogu manipulirati sa pccardctl ili sa cardctl ovisno o verziji Suse-a kao npr.:

>pccardctl eject
>pccardctl insert

Ova kartica ima par posebnosti. Jedna je da treba inicirati Radio Interface. To se moze samo ako je seriski port otvoren s brzinom 57600. Onda treba poslati slijedecu komandu:

AT+CFUN=1

Ako nazad dobijete OK odgovor time ste inicirali Radio Interface. Od tog momenta port mozete otvarati vecim brzinama sto je vazno ako zelite vezu brzu od obicnog dial-upa.

Slijedece sto trebate poslati kartici je vas PIN. To radite s:

AT+CPIN=xxxx

xxxx je vas PIN.

PPPD scripte

E da bi vam ovo sve bilo lakse napravio sam pppd skripte koje to rade malo vise automatski samo morate promjeniti xxxx u vas PIN. (ovo su modifikacije skripti nadenih na GlobeTrotter (GPRS) Howto )

Ove skripte se pokrecu s:

pppd call vodafones

Sada se mozemo probati spojiti. Za to su nam opet dostupne skripte ali moram naznaciti da vrlo vazni inicijaciski stringovi u njima jer inace veza vrlo brzo puca. I ako, nakon startanja skripte, dobivate “heroglife” na ekranu probajte promjeniti baudrate iz 921600 u 230400.

Ukratko kako se ja spajam:

 >pccardctl eject
 >pccardctl insert
 >pppd call vodafones
 >pppd call vodafone

Ako se zelite odspojiti napravite sve kao za standarni izlaz iz konzolnih programa (Ctrl+c).

Evo to bi bilo to.
