I'm using ComPort on Delphi XE2 and it works fine (for sending SMS)
Sending multiple SMS can be a problem.
Tried to set a 5000ms delay and it works well.
But how to make it "smart" by capturing return value from RxChar?
anyone got an idea?
when sending SMS we need to send minimum 2 commands
1. AT+CMGS="1234567890" + #13#10
2. <your message here> + #26
Problem is, after 1st step we need to wait for RxChar to return ">" before sending message
After sending message (step 2) RxChar should be returning sending status whether OK or ERR
Then we could proceed to next message.
Is there anyone have a better idea than delaying 5000ms?
thanks in advance
