[Serusers] SMS gateway using a mobile phone

Hi, Am trying to get SER to send SMS messages out via my SER server serial/comm port connected to a Motorola Timeport P7382 mobile phone but am having trouble because of SER "sms.so" module keep trying to register the SMS center number; syslog snippet. <snip> Apr 1 18:32:28 gits /usr/sbin/ser[18276]: INFO:initmodem: Checking if Modem is registered to the network Apr 1 18:32:30 gits /usr/sbin/ser[18266]: NOTICE:initmodem: Waiting 2 sec. before retrying <snip> The mobile phone already register to the SMS center number thus re-registering is not required. "sms.so" module doesn't seems to pick up the message that the mobile phone have already registered to the SMS center number and I have to amend and recompile "libsms_modem.c" because the mobile phone do not recognise AT+CREG command but AT+CSCA command. To test whether the mobile phone is able to send SMS messages out via the serial/comm port, I used Stefan Frings "SMS Server Tools" by commenting the config file from registering the SMS center number and it managed to send out sms messages. However on SER "sms.so" modules, I have no idea how to stop it from registering the SMS center number. From the "../sms/README" file, it did mention that "c=SMS_center" is mandatory. That looks like not registering to the SMS center is a no-no. :-( Other than changing some words here and there of the source code via gut feel, I don't have any experience in C thus am yelping for help here. Btw, the modem baud rate on "sms.c" only supports up to 38400 and that won't work with my mobile phone, thus have to add a line for 57600 baud rate. Maybe is already added in the latest CVS. Am using the stable version source. Below is my "ser.cfg".
