TD1208 EVB - AT$ commands

Hello,

I'm using the TD1208 EVB connected to the UART of a separate MCU. I can send commands like ATZ, AT&V, ... but sending AT$ commands doesn't work. This is what I see with a putty connection to my MCU for the AT$ commands - I have a callback function in my C/C++ program that displays the output from the TD1208). After this message my firmware keeps hanging.

Output:

TD1208 EVB Test
A▒▒▒▒▒▒

Any idea why almost all commands work but not the AT$ commands?

Thanks.
Guy
