Trying to send any AT command hangs at this page:
get_atcommand never responds:
Environment
Running current stable SimpleAdmin with just Tailscale installed, Tested in Firefox & Chrome on Debian 12, validated with a second modem.
@dr-dolomite commented on GitHub (Jun 3, 2024):
I suggest to use to development branch. It is much stable (simpleadmin) and received a lot of fixes.
@MickMorley commented on GitHub (Jun 19, 2024):
Hi @dr-dolomite, I found your Simple Admin 2.0 yesterday. It looks great! When will the changes in the development be pushed to the main branch?
That's great that its at a point where its stable.
@danry25 commented on GitHub (Aug 29, 2024):
I tracked this down to /dev/ttyOUT2 not responding on some RM520N-GL's even after reflashing the firmware with QFirehose, it appears the wait time just endlessly ratchets up as minicom is attempted again and again.
If we could switch to /dev/ttyOUT if /dev/ttyOUT2 does not respond (eg: when line 28 is run) this would mitigate the underlying firmware bug.
Here is where /dev/ttyOUT2 is called:

Main branch is archive and directory only now.
These issues don't exist on the development branch.
See the updated readme in main
@danry25 commented on GitHub (Feb 7, 2025):
This bug persists in the current SDXLEMUR branch, to fix it edit DEVICE=/dev/ttyOUT2 in /usrdata/socat-at-bridge/atcmd to drop the two.
Symptoms include hanging after running an AT command using the atcmd prompt in adb shell, and no values being displayed in SimpleAdmin 2.0
