The Advanced Serial Port Monitor alternative

Monitoring a serial line is half the job. Omni Console sniffs the line and decodes it — Modbus, DLMS, M-Bus, IEC 62056-21, MASS, DNP3, BACnet MS/TP, HART and more — so you read meaning, not just bytes.

Why teams switch

From bytes to meaning

Decoded, not just dumped

Where a monitor shows bytes, Omni Console shows Modbus registers, DLMS OBIS, M-Bus records and more.

Sniff and understand

Tap a live line and read both directions as a real protocol, in one trace.

Windows and Linux

Serial sniffing on Linux and Windows — the same tool everywhere.

Flows + AI

Automate beyond send-scripts with flows, and drive it all with an AI agent.

Where Advanced Serial Port Monitor fits

Advanced Serial Port Monitor is a handy Windows utility for watching and sending raw serial data, with a long track record. If all you need is to observe or replay bytes on Windows, it does the job. Omni Console is the better fit when you want that traffic decoded as a protocol, paired request-to-response and turned into labelled values — plus builders, flows, remote SSH and AI — on Windows and Linux.

What does Omni Console add over a serial monitor?
A serial monitor shows you the raw bytes. Omni Console decodes them — pairing requests with responses and turning payloads into labelled Modbus, DLMS, M-Bus, IEC 62056-21 and MASS values — and adds builders, flows and AI control.
Can it sniff a live line?
Yes. Sniff mode inserts Omni Console transparently and decodes both directions, on Windows and Linux. See sniff mode.
Is it Windows-only?
No — Omni Console runs on Windows and Linux.
