Data Mode with AT commands


i am using the usb ports on HL7800 on a linux enviroment. I was wondering how to use the data mode with the AT commands such that i can use multiple ports. Sending ‘+++’ does not work to return to command mode.

Thank you,

Hi zaki_ncbistudent,

If you make PPP dial up, you need to make sure no <CR/LF> added at the end of “+++”.
If you make KUDP/KTCP/KHTTP/ service, you need to use “–EOF–Pattern–” (no <CR/LF> at the end of the string) to exit the data mode.
