DC 9.62 PPP Chat.lib - chat_init problem

I’m attempting to use PPP over serial with the LP3500 and have run into a problem with the ifconfig DIALUP_SEND_EXPECT macro.

I’d like to send a token “AT” that includes only. By default, a is appended to the token. In the function description for chat_init, it indicates that a # can be prefixed to suppress the which works. However, if I try to define the token as “#AT\r” the is not appended. Trying the example in the function description, '#
’ does not send anything. Any suggestions on how to append only the ?

Update: found the solution: “#AT\r”
