Support text mode sms send and receive

Hi, all: Our project used ZTE EVDO modem. But this modem only supports sending and receiving sms with text mode. I have modify oFono gatchat code to support this. But it conflicted with original gatchat architecture. Does oFono plan to support text mode sms send&receive? Following are some AT commands: Send sms: AT^HCMGS=<da><CR><msg><ctrl-Z> <da>: Receiver phone number <msg>: value of message content <ctrl-Z>: end character 0x1A (UCS2 format is 0x001A) Firstly, send ^HCMGS=<da> end of <CR>, TE waits MS response <CR><LF><greater_than><space> (IRA 13, 10, 62, 32). Secondly, send message content and end of <ctrl-Z>. <msg> example, for string "oFono" : chat command is 0x6F, 0x46, 0x6F,0x6E,0x6F, end character is 0x1A if <format> is CDMA ASCII chat command is 0x00, 0x6F, 0x00, 0x46, 0x00, 0x6F,0x00, 0x6E,0x00, 0x6F, end character is 0x00, 0x1A if <format> is CDMA UCS2 BE (PS: <format> can be set by another AT command) Receive sms: ^HCMT: <callerID>,<year>,<month>,<day>,<hour>,<minute>,<second>,<lang>,<format> ,<length>,<prt>,<prv>,<type><CR><LF><msg><ctrl-Z><CR><LF> Important tag: <callerID>: Sender phone number <format>: ASCII or UCS2 BE <length>: Message content length, not contain <ctrl-Z> <msg>: value of message content, same as above command Best Regards Su Yong
