Identifikace pod Linuxem

ttyS14 at I/O 0x400 (irq = 3) is a 16C950/954

Postup zprovoznění pod Linuxem

Petr Vandrovec napsal patch a postnul jej do linux kernel mailing listu.

 

Je tam napsany i navod na zprovozneni.

(Smyslem patche je probudit MC45 ze sleep módu, ve kterém se nachází po startu. Jiná možnost, jak MC45 probudit je něj zavolat z jiného telefonu; to samozřejmě lze použít pouze k otestování funkčnosti bez nutnosti hned patchovat jádro, nikoliv k běžnému použití...)

Poznámka

1) Patch funguje a karta prijima AT prikazy na vanilla jadrech. Aplikovat patch do kernelu FC3 slo, ale karta nebezela. Podobnou zkusenost meli lidi i s MDK jadry.

 

2) Nevim jestli je nekde archiv lkml v plain textu a tak jsem ten patch vykousany z html dal sem.

 

3) Spojeni k inetu nahazuju takto:

rm /dev/modem &>/dev/null
ln -s /dev/ttyS14 /dev/modem >/dev/null
setserial -bG /dev/modem baud_base 1152000 &>/dev/null
nohup wvdial &>/dev/null &

4) cat /etc/wvdial.conf

[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
Init1 = ATZ
Init2 = AT+CGDCONT=1,"IP","INTERNET"
Init3 =
Area Code =
Phone = *99***1#
Username = internet
Password = none
Ask Password = 0
Dial Command = ATDT
Stupid Mode = 1
Compuserve = 0
Force Address =
Idle Seconds = 0
DialMessage1 =
DialMessage2 =
ISDN = 0
Auto DNS = 1

Protože patch na Jikosových stránkách už není, dovolil jsem si ho přetisknout:
