[BUG] KA-50 Targeting Mode Control Panel - Head-on airborne target button issue

[Jocman]

DCS Unified 2.9.3 (DCSBIOS Fork)

Ka-50 Black Shark 3 - Targeting Mode Control Panel

WEAPONS_FORWARD_HEMI_TARGET_BTN

Testing the Bort snippet in Socat (with no DCS running) pushing the button I expect to read the messages:

WEAPONS_FORWARD_HEMI_TARGET_BTN 1 WEAPONS_FORWARD_HEMI_TARGET_BTN 0

but I get instead only:

1 0

and, if I run DCS, I don't see the virtual button moving.

To Reproduce

Expected behavior

I expect tho read the messages sent WEAPONS_FORWARD_HEMI_TARGET_BTN 1 WEAPONS_FORWARD_HEMI_TARGET_BTN 0 but I get only 1 0

Screenshots

Additional context

With the support (and effort and time) of Vinc_Vega, I found that there's some internal DCSBIOS issue, as if I load a simple sketch like: ` #define DCSBIOS_IRQ_SERIAL #include "DcsBios.h"

/* paste code snippets from the reference documentation here */ DcsBios::Switch2Pos weaponsForwardHemiTargetBtn("WEAPONS_FORWARD_HEMI_TARGET_BTN", 3);

void setup() { DcsBios::setup(); }

void loop() { DcsBios::loop(); }

`

I get the correct behaviour (the full messages sent correctly).

But switching to RS_485 bus (as per my system):

`//#define DCSBIOS_IRQ_SERIAL

#define DCSBIOS_RS485_SLAVE 126 //Nr. massimo: 126

/* The Arduino pin that is connected to the /RE and DE pins on the RS-485 transceiver. */ #define TXENABLE_PIN 2 //PIN RISERVATO PER PROTOCOLLO 487

#include "DcsBios.h"

/* paste code snippets from the reference documentation here */ DcsBios::Switch2Pos weaponsForwardHemiTargetBtn("WEAPONS_FORWARD_HEMI_TARGET_BTN", 3);

void setup() { DcsBios::setup(); }

void loop() { DcsBios::loop(); }`

I get only 1 and 0

The issue seems be limited to RS_485 bus, as in IRQ_SERIAL mode it works correctly.
