I am new to OPENBSD and smstools too...
I have installed smstools on openbsd and am trying to run smstools on it but I am getting the following error in the logs

2014-09-01 14:58:03,7, GSM1: put_command expected (OK)|(ERROR), timeout occurred. 2.
2014-09-01 14:58:03,7, GSM1: <-

2014-09-01 14:58:18,2, GSM1: Failed to initialize modem GSM1. Stopping.
2014-09-01 14:58:18,2, GSM1: Modem handler 0 terminated. PID: 22955, was started 14-09-01 14:55:51.

Here is my smsd.conf

devices = GSM1
#devices = GSM1, GSM2
loglevel = 7

# After initial setup this might be a good option; notices by default,
# but debug logging is buffered and stored to another file after an error.
#loglevel = 5
#smart_logging = yes

# setuid() to this user:
user = _smsd
# it's possible to setgid too, but default is the set of
# groups from /etc/groups

pidfile = /var/log/smsd/
infofile = /var/log/smsd/

#logfile = syslog
logfile = /var/log/smsd/smsd.log

# A sample USB device with typical broken rtscts, so use
# a send delay to reduce the risk of overruns. Some PC cards
# also break rts/cts. On some 3G cards you might be able to
# use the control device for SMS simultaneously with using
# the data device for a PPP connection.
# For this one I have set incoming=no so it doesn't pull
# the existing messages off the phone.
device = /dev/cua00
incoming = no
rtscts = no
send_delay = 20

I have added _smsd user in /etc/group as

ownership of /dev/cua00 is as follows
# ls -l /dev/cua00
crw-rw---- 1 _smsd dialer 8, 128 Sep 1 15:47 /dev/cua00

I am unsure of where the problem lies....
Can you please help me ...

Thanks in Advance,

i have the same problem today.
In my case, i think, that the problem is in the usb Hub with modem extension.

Anyway, If you solve, please post solution here. i'll do the same.
