Question socketcom serial adaptor with ricochet modem 

Forum: PCMCIA Serial and Modem Issues

Hi,

I am having difficulty with Socketcom serial adaptor S-I/O card when I use it with my ricochet cellular modem. The card is recognized, ttyS1 is configured, and a ppp connection is established, however pppd fails to configure the interface with an IP address. My ricochet setup works with the builtin serial port, i.e. ttyS0 (unfortunately this requires me to carry a port replicator).

I am including some diagnostics information. Did anyone seen similar problems or have any suggestions for me to try?

Thank you

Cengiz
