154. Hyperterminal e character with GSM alphabet value of binary 0 will terminate any C string This is because the 0 is defined as C string end tag Therefore the GSM Null character may cause problems on application level when using a C function as strlen This can be avoided if it is represented by an escape sequence as shown in the table below By the way this may be the reason why even network providers often replace with in their SIM application e Other characters of the GSM alphabet are misinterpreted by an ASCII terminal program For example GSM 6 as in Borse is assumed to be in ASCII thus resulting in B rse This is because both alphabets mean different characters with values hex 7C or 00 and so on In addition decimal 17 and 19 which are used as XON XOFF control characters when software flow control is activated are interpreted as normal characters in the GSM alphabet When you write characters differently coded in ASCII and GSM e g A O U you need to enter escape sequences Such a character is translated into the corresponding GSM character value and when output later the GSM character value can be presented Any ASCII terminal then will show wrong responses Examples for character definitions depending on alphabet MC55_ATC_V01 05 Page 19 of 469 2 10 04 Confidential Released MC55 AT Command Set SIEMENS 1 5 Supported character sets Mobile GSM 03 38 GSM character Corresponding ASCI

MENS 1 6 Flow Control Mobile 1 6 Flow Control Flow control is essential to prevent loss of data or avoid errors when in a data or fax call the sending device is transferring data faster than the receiving side is ready to accept When the receiving buffer reaches its capacity the receiving device should be capable to cause the sending device to pause until it catches up There are basically two approaches to regulate data flow software flow control and hardware flow control The High Watermark of the input output buffer should be set to approximately 60 of the total buffer size The Low Watermark is recommended to be about 30 The data flow should be stopped when the capacity rises close to the High Watermark and resumed when it drops below the Low Watermark The time required to cause stop and go results in a hysteresis between the High and Low Watermarks In Multiplex mode it is recommended to use hardware flow control 1 6 1 Software flow control XON OFF flow control Software flow control sends different characters to stop XOFF decimal 19 and resume XON decimal 17 data flow The only advantage of software flow control is that three wires would be sufficient on the serial interface 1 6 2 Hardware flow control RTS CTS flow control Hardware flow control sets or resets the RTS CTS wires This approach is faster and more reliable and there fore the better choice When the High Watermark is reached CTS is set inactive u
