Appendix A AT Commands +IPR=-Fixed DTE Rate Use this command to set the DTE to DCE transmission rate. There are twelve fixed transmission rates used by the DTE to communicate with the DCE. This commands select one of the predefined transmission rates. If a rate is entered which is not supported, the transmission rate defaults to the next lower rate. +IPR=0 +IPR=300 +IPR=1200 +IPR=2400 +IPR=4800 +IPR=9600 +IPR=19200 +IPR=38400 +IPR=57600 +IPR=115200 +IPR=230400 +IPR=460800 +IPR=921600 Automatic rate detection (default). 300 bits/s. 1200bits/s. 2400 bits/s. 4800 bits/s. 9600 bits/s. 19200 bits/s 38400 bits/s. 57600 bits/s. 115200 bits/s. 230400 bits/s. 460800 bits/s. 921600 bits/s. +MA=,, ...-Modulation Automode Control Use this parameter to define a list of modulations that the soft modem may use to connect with a remote modem for answering or originating automode (automatic modulation negotiation) data calls. The list acts as an extension to the modulation specified by the +MS= command. The modulation identified by in the +MS command limits the values in the +MA carrier list. Modulations which exceed the rate set by the +MS command, generate an ERROR result code and are not implemented by the soft modem. values omitted from the list are not available for automode negotiation and are not used in automode negotiation even when the modem is capable of generating the modulation. +MR=-Modulation Reporting Control Use this command to enable or disable modulation report result codes. When the modulation report is enabled, the DCE transmits the +MRR: , and the +MCR: intermediate result codes to the DTE. The reported is the current modulation, for example, V.34. The reported is the transmit rate in bits per second or is zero if negotiation fails. The is the receive channel rate and is only reported when different receive and transmit rates have negotiated. The intermediate result codes are transmitted after the modulation and the 55
