Hi,

After reboot, get the expected output

OK

Manufacturer: Sierra Wireless, Incorporated

Model: MC8790V

Revision: K2_0_7_24BAP C:/WS/FW/K2_0_7_24BAP/MSM6290/SRC 2010/02/09 00:19:18

IMEI: 012376000067082

IMEI SV: 15

FSN: C681542057310

3GPP Release 5

+GCAP: +CGSM,+DS,+ES

OK

+CSQ: 1,99

OK

etc.

After I run my program, I do this again and the first time AT returns ERROR, then its ok.

If USB doesn’t need baud rate, are there other settings it does or doesn’t need? My code looks a lot like the termios part of

I did get a response:

“ERROR”

then another AT command and “OK”

I assume that something’s wrong with the code/port setup. I intermittently get “ERROR” or 0 bytes.

How do I know the correct settings for this port?

Is it documented?

I’m now using 115200 baud.
