Serial Modem Gateway documents
A Serial Modem Gateway document is required when a GSM modem is connected to the server via a
serial port (COM port). The physical connection may be USB, Bluetooth or using a RS-232 cable. In
production environments only the RS-232 connection should be used. The other connections are
less stable and require additional configuration settings.
In this document we assume the modem is connected via a RS-232 cable to a serial COM port. The
modem was tested and responded with OK to the AT command.
Specific settings for Serial Modem Gateway
Directions: specify if the modem is used for sending SMS messages (outbound) and/or

receiving SMS messages (inbound)
COM port: select the COM port from the list or enter the name of the port. The name is

case sensitive and should correspond to the name reported by Windows. Do not specify
the colon after the COM port name
COM speed: this speed must correspond to the speed that the modem is using. Some

modems may operate at multiple speeds. It is recommended to test the communication
to the modem at the specified speed via a test program (see the help document Choice
and installation of the modem
)
Manufacturer - model: communication between the computer and the modem is based

on AT-commands. Most modems are using the same set of AT commands. Some
modems deviate from the standard. Specify Generic if your modem is not listed.
PIN code: the PIN code of the SIM card in the modem. Sms4Domino may lock the card

if a wrong Pin code is specified. Sms4Domino has no tools to reset the Pin code.
