I am unable to control my SL5011 from the serial port, and effectively at all since I changed the configuration.
I was able to connect to my SL5011 through USB, but wanted to use the serial interface for communication with another device. I connected to it using USB and issued two commands:
AT!OEM=176 which allows me configure certain settings
!SERIALPORTMAP=79 which is supposed to enable the UART1 interface.
Now, when I attempt to connect to the serial port in hyperterminal I get an error: Unable to connect to Port X, Please check your port settings. If I connect to the port in the discovery manager I can sometimes connect but am unable to issue any commands, and most of the time I get an error saying that something else is already connected to the port. What’s worse is that now the USB doesn’t work to issue AT commands because the second command above sets the serial port as the only way to do so.
Can anyone help me figure out what is going on here? Short of that, can anyone help me reset my modem so I can at least use the USB for at commands again?
