problemy s ppp

[Milan Plsek]

Ahoj,
rad bych poprosil o radu. Takto vypada log ppp, kdy mi spojeni bez 
problemu projde:

Nov  2 15:26:24 blesk mgetty[777]: data dev=ttyS0, pid=777, caller='none', conn='33600/ARQ', name='', cmd='/usr/sbin/pppd', user='/AutoPPP/'

...
ze stejneho PC (win95 ) zkousim jiny port (/dev/ttyM* - ktery pochazi z
karty MOXA). Dopadne to takto: 

Nov  2 15:20:36 blesk mgetty[535]: data dev=ttyM1, pid=535, caller='none', conn='33600/ARQ', name='', cmd='/usr/sbin/pppd', user='/AutoPPP/'

Nov  2 15:21:13 blesk pppd[535]: Connection terminated.
Nov  2 15:21:13 blesk pppd[535]: Exit.

a ve Win se objevi hlaska: "Dial-up networking couldn't negotiate a
compatible set of network protocols you have specified in serve-type
settings (BTW: nastaveni jsou uplne stejna jako jako u predchoziho
spojeni). Check your network configuration bla bla...

ppp/options:
-detach
38400
lock
modem
crtscts
asyncmap 0
proxyarp

ppp/options.ttyM1:
auth
+pap
:194.30.0.1
ms-dns 194.0.0.41

Nemuze mit vliv to, ze jmeno zarizeni neni /dev/ttyS*, ale /dev/ttyM* ?  
/dev/ttyS0 pouzivam pro jeden dial-up /dev/ttyS1 pro pevnou linku a porty
/dev/ttyM0../ttyM04 jsou pro moxa kartu na dial-upy. 
Jeste jedna poznamka, skript dodavany k softwaru te karty vytvari
automaticky soubory /dev/ttyM* a take /dev/cum*, neni mi poradne jasne k
cemu jsou ty druhe jmenovane. Byl by nekdo tak hodny a vysvetli mi to ?

Budu vdecny za kazdou radu. Dik
