I've been using one for years, although not for sending. I configured it
for class 2.0 operation. This is a snippet of my configuration:

...
ServerTracing:          1
SessionTracing:         11
RecvFileMode:           0640
LogFileMode:            0640
DeviceMode:             0660
RingsBeforeAnswer:      1
SpeakerVolume:          off
GettyArgs:              ""
TagLineFont:            etc/lutRS18.pcf
TagLineFormat:          "Da %%l|%c|Pagina %%P di %%T"
MaxRecvPages:           25
...
ModemType:              Class2.0        # use class 2.0 interface
ModemRate:              19200           # DCE-DTE communication rate
ModemFlowControl:       rtscts          # hardware flow control
#
ModemNoFlowCmd:         AT&H0&I0&R1     # setup modem for no flow control
ModemHardFlowCmd:       AT&H1&I0&R2     # setup modem for hardware flow
control
ModemSoftFlowCmd:       AT&H2&I2&R1     # setup modem for software flow
control
#
ModemSetupDTRCmd:       ATS13=1&D2      # setup so DTR drop resets modem
ModemSetupDCDCmd:       AT&C1           # setup DCD reflects carrier
ModemResultCodesCmd:    ATQ0X3
#
ModemSetVolumeCmd:      "ATM0 ATM1 ATM1 ATM1 ATM1"
#
# Modem does not support HDLC frame tracing; we add this just
# to eliminate spurious ERROR results that confuse the naive.
#
Class2BUGCmd:           AT+FBU=0
#
# The modem doesn't support copy quality checking, even though it
# returns (0-2,0-2) for AT+FCQ=?; therefore we override the query
# response so that the server will do copy quality checking.
#
Class2CQQueryCmd:       !(0),(0)        # override modem response
#
# Disables the reporting of bad frames by the modem.  This
# overcomes a firmware problem in the x2 and V90 Sportsters.
# It is not necessary for the Courier modem.
#
Class2NRCmd:    AT+FNR=1,1,1,0
#
# USR modems violate Class 2.0 specs and do not send RTC itself
#
Class2SendRTC:  yes
#
# +FAP=? not supported on this modem, gives ERROR in ServerTracing
#
Class2APQueryCmd:       none
# Poor line quality suggests reducing line speed.
Class2DCCQueryCmd:      !(0,1),(0-2),(0-2),(0-2),(0-1),(0),(0),(0-7)
...

Please note that Class2DCCQueryCmd may not be strictly necessary, we
use it because of poor line quality.

Hope this helps,
Davide Bolcioni
