Vysvetleni:
Mam k dispozici jednak 'Eurotel Data Nonstop' na dedikovanem Siemensu MT50 pres seriovy port, jednak zminenou GPRS kartu od T-Mobile.
U T-Mobile lze dosahnout (zrejme diky vyssim kodovacim schematum) vyssi maximalni rychlosti, videl jsem >6kB/s (mereno wgetem), rychlost vsak velmi kolisa a casto se nekolik vterin neprenese ani byte.
Eurotel jede sice "jenom" 5.5kB/s, zato jede _porad_, bez zavahani.
Z meho pohledu je tedy pouzitelnost Eurotelu nesrovnatelne vysii nez pouzitelnost T-Mobile...
Jeste horsi je, ze s T-Mobile GPRS kartou spojeni kazdou chvili (prumerne asi jednou za hodinu) vytuhne a je nutne kartu vytahnout a znovu zastrcit (odmita komunikovat i v minicomu). Eurotel oproti tomu jede nonstop nekolik dnu.
A ted tedy konecne ty konfiguraky:
sh-2.05b$ cat /etc/ppp/peers/option nodetach debug noipdefault defaultroute lock /dev/ttyS17 115200 connect /etc/ppp/option sh-2.05b$ cat /etc/ppp/option #!/bin/bash /usr/sbin/chat -v -t30 \ '' atz \ OK at+cgdcont=1,\"IP\",\"internet.t-mobile.cz\" \ OK atd*99***1# \ CONNECT '' sh-2.05b$ cat /etc/ppp/options lock noauthVytaci se pomoci 'pppd call option'.
