Hi guys, my SIM900D GSM/GPRS modem works fine and smoothly using the RS232 connection. Is there anyone of you knows how to configure it using the UART to USB connection? (USB connection perse'). I am using the smstools3-3.1.14 version of the smstools3.

Hope anyone knows.

Here is my current configuration of smsd.conf:

# device
devices = GSM1

# folder used in the sms
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
incoming = /var/spool/sms/incoming
failed = /var/spool/sms/failed
sent = /var/spool/sms/sent
stats = /var/spool/sms/stats

# additional setting
stats_interval = 0
status_interval = 1
logtime_ms = yes
logfile = /var/log/smsd.log
pidfile = /var/run/smsd.pid
loglevel = 7
receive_before_send = yes
eventhandler = /usr/local/bin/mysmsd
autosplit = 3
max_continuous_sending = 7200
trust_outgoing = yes
report = /var/spool/sms/report

[queues]
GSM1 = /var/spool/sms/GSM1

[provider]
# Examples for Philippines
GSM1 = 63907,63908,63909,63910,63912,63918,63919,63920,63921,63928,63929,63930,63938,63939,63948,63949,63989,s214,s258
