i just installed a new gsm modem through my serial port (COM1). i issued AT-commands in hyperterminal and the commands went well.
i am developing a software in visual basic 6 that would send and receive sms. in hyperterminal you press CTRL+Z to send the message under the AT+CMGS command. my question is what is its equivalent in visual basic 6. please send me a sample code. also as i was trying to look at other sms forums, i saw lines with chr$(13). what does this mean. thanks in advance.
