This I/O Server provides services for sending and receiving SMSs and events generation for incoming calls via serial GSM modem.
The employed protocol complies with the AT commands set specified by the GSM standard set. It has been tested on the GenPro 16e and GenPro 18e modems by Erco&Gener and on the AirLink FXT009 modem by Sierra Wireless.

Communication
Employ a RS-232 straight cable to connect the modem directly to HSYCO or to an Ethernet/RS-232 gateway.
RS-232 parameters:
| Baud rate | 9600 (GenPro modems) |
| 115200 (default on AirLink FXT009 modems) | |
| Data bits | 8 |
| Stop bit | 1 |
| Parity | none |
| Flow control | RTS/CTS |
HSYCO Configuration
Options
| ID | Default | Values | Description |
|---|---|---|---|
| pin | <code> | 4-digits PIN code of the SIM card (if used) | |
| gui | true | true | enable support for the UI object, UISET actions and USER commands |
| false | disable UI support | ||
| inboxsize | 10 | n ≥ 0 | the number of incoming messages to display in the UI object |
| countrycode | <code> | the default country code (e.g. “39”, for Italy) to be used when not otherwise specified. If omitted all provided numbers shall include the country code
| |
| srvc | <number> | phone number of the SMS service center (use the international format, e.g. +393492000200). If not specified, the default number saved on the SIM card will be used. If not available, the driver will not be able to sent SMS messages | |
| resend | 4 | n ≥ 0 | number of sending attempts on an outgoing SMS in case of error |
Datapoints
| ID | Value | R/W | Description |
|---|---|---|---|
| connection | online | R | connection established |
| offline | R | HSYCO can't connect to the modem | |
| sms.<num> | <text> | R | an SMS message has been received form the number <num>[Note 2] with <text> as body |
| W | send an SMS message to the number <num>[Note 1] with <text> as body | ||
| call | <num> | R | incoming call from number <num>[Note 2] in progress. An event is generated for each “ring” during the call |
| unknown | R | incoming call from an unknown number in progress | |
| sms.<num>.sent | <mr> | R | a message has been successfully sent to the number <num> and the message reference number is <mr> |
| sms.<num>.errors | <val> | R | an error occurred while sending a message to number <num>. The value <val> is an increasing counter of the occurred errors since the I/O Server started |
| signal | {0 ... 31} | R | the GSM signal level has the reported value (ranging from 0 to 31) |
| unknown | R | the GSM signal level is unknown |
- Note 1
- If the option 'countrycode' is used, then the country code will be automatically added to the specified numbers, unless the latter begins with a '+' character. For instance, assuming the option 'countrycode' is set to “39”, the addressee number “3480077000” will be automatically changed to “+393480077000”, while the number “+46765007700” will remain unchanged. If, on the other hand, no default country code has been specified, then the addressee numbers must always be provided prepending the country code.
- Note 2
- The numbers are reported as sent from the modem and the format may vary depending on the number itself and the modem settings. If the reported number is an international number, then a '+' will be prepended to it, unless the country code is equal to the value of the 'countrycode' option. In the last case the country code will be omitted. In some cases, the sender number field might also be replaced by an alphanumeric string.
