cygwin port of Kannel

Hello,
I am trying to use the cygwin port of Kannel on an NT / 2K machine.
I have a problem in using a GSM Modem (Siemens-tc35) as the SMSC.
When I try to connect to the com port, the bearer box shuts down saying

2002-08-21 06:36:08 [0] ERROR: Failed to create Smsc wrapper
2002-08-21 06:36:08 [0] PANIC: Cannot start with SMSC connection failing

Can anyone help me in this please?

Also, although the user guide specifies that I can have a group called
modems
group = modems,
the moment I add this line into the kannel.conf, the bearer box refuses to
start.

Any help / suggestions in this regard are welcome.

Thank you very much and best rgds
Anu
