Question

When using gsmctl -U command to send USSD commands the output in /tmp/ussd only contains the first line. Some providers will send multiline USSD responses. Those can't be displayed correctly. Unfortunateley, the "gsmctl" binary is not in the GPL package.

Used firmware: RUT9XX_R_00.06.07.4

Used device: RUT950

Sending:

gsmctl --ussd "**51*012345678901#"

Receiving:

cat /tmp/ussd

Hi,

I have the same issue on RUTX12:

CURRENT FIRMWARE INFORMATION

Firmware version	RUTX_R_00.02.06.1
Firmware build date	2021-02-11 17:38:18
Primary modem firmware version	EG06ELAR03A05M4G
Secondary modem firmware version	EG06ELAR03A05M4G
Kernel version	4.14.195

FIRMWARE AVAILABLE ON SERVER

Firmware version	Newest version installed on the device
Modem firmware version	Newest version installed on the device

I've tried a few variations of using the USSD code:

gsmctl -A AT+CUSD=1,"*177177#",15

gsmctl -U "*177177#"

In both cases, I get just the first line of the response, not the rest. Also, my output is visible on /tmp/ussd_3_1_1 not /tmp/ussd, but that's. non-issue, just something I haven't  noticed in the community.

Regards,

Hi,

Could you please showcase how you're trying to send USSD commands and how you receive them?

So wait, you used this USSD gsmctl command and what do you exactly need to get in the /tmp/ussd and what it outputs you instead?

I need to following output:

"Rufumleitung ohne Bedingung

Telefonie: 43012345678901

FAX: 43012345678901

Daten: 436012345678901"

(number modified, it's a call forward setting from the ISP).

Instead the /tmp/ussd file shows only this:

2021-02-05 14:10:05 "Rufumleitung ohne Bedingung

Thank you, I reported this to RnD.

Will let you know if anything comes up.
