Did your mail agent put those blank lines between "group = smsc"
and "smsc = at"? Or, are they actually in the configuration file?
If you do have blank lines in there, then remove them.
Support for the GSM Modem as a virtual SMSC is found in
gateway/gw/smsc/smsc_at.c and gateway/gw/smsc/smsc_at.h.
The error you were getting "Unknown SMSC type 'at'" only happens
after the checks for all the smscs.
That usually happens if the smsc is mispelled, has extra characters
(e.g. double-byte characters instead of ASCII) in the name, or
incorrect parsing of the configuration file.
The bearerbox execution sequence is:
- gateway/gw/bearerbox.c:main() calls
gateway/gw/bearerbox.c:init_bearerbox().
- init_bearerbox() calls gateway/gw/bearerbox.c:start_smsc().
- start_smsc() calls gateway/gw/bb_smscconn.c:smsc2_start().
- smsc2_start() calls gateway/gw/smscconn.c:smscconn_create() for
every "group = smsc" encountered.
- smscconn_create() processes the configuration group and then
creates the smsc client instances based on the configuration.
It is here that checks the "smsc = xxx" entry in the following
sequence:
"fake" --> smsc_fake_create()
"cimd2" --> smsc_cimd2_create()
"emi" --> smsc_emi2_create()
"http" --> smsc_http_create()
"smpp" --> smsc_smpp_create()
"at" --> smsc_at2_create()
"cgw" --> smsc_cgw_create()
"smasi" --> smsc_smasi_create()
"oisd" --> smsc_oisd_create()
The name comparison is byte-for-byte. Therefore, if the name does not
exactly match the byte sequence 0x61 0x74 ("at"), 0x41 0x54 ("AT"),
0x41 0x74 ("At"), or 0x61 0x54 ("aT"), then the match will fail to
find a declaration for the GSM modem smsc configuration.
Should the smsc not be one of the above, it punts the evaluation over
to gateway/gw/smsc/smsc_wrapper.c:smsc_wrapper_create() for the older,
less support smsc client implementation.
- Inside smsc_wrapper_create() it calls gateway/gw/smsc/smsc.c:smsc_open().
- smsc_open() compares the smsc type to the following older implementations:
"cimd"
"emi_x25"
"sema"
"ois"
If the smsc type is none of the above, then it will issue the:
Unknown SMSC type '...'
message and abort the attempt to create and instance of the smsc client.
See ya...

**>group = modems
**>id = siemens-mc35

**>need-sleep = true
