indication. Following commands and data are directly transferred between PC and
GSM/UMTS module so that it behaves as a fax class 1 modem for the PC.
Outgoing fax and data connections are always possible via the serial interface
without special configuration. If the dail command (ATD) is detected, this command is
given to a free GSM/UMTS module regarding the net access numbers, and this
module is connected transparently to the PC, so that the PC again operates as if
connected to a fax class 1 modem. If the PC sent other commands immediately
before the dial command which are not processed by the coM.sat ISDN Basic UMTS
itself, these commands are also sent to the GSM/UMTS module before dialling.
Further information on fax and data connections can be found in chapters 4.5 and
4.6.
Note 1: The SIM cards used must support fax and data calls.
Note 2: If fax and/or data shall be exchanged with the use of a PC, but the PC
software did not activate the serial interface, these calls will be rejected.
