Hi, I'm trying to connect my mount to my M1 Pro Macbook but while it is possible via wifi, I can't find a way to make it work wired. The message I get is "Failed to connect to port (/dev/cu.usbserial). Error: Port failure Error: No such file or directory. Check if device is connected to this port."  Do you have any ideas what is wrong?

I don’t know if Mac is like Linux in that the DTR on the serial cable needs to be reversed. If you are using a FTDI chip then you can download FTDprog which allows you to reverse the DTR signal. That was always an issue when connecting to kstars on Linux.

W Gadecki: give a try to indigo drivers and their suite for Mac/Apple
it works well for me under linux

The firmware installed is the new one.

One more thing - the mount works perfectly well on a MacBook air I borrowed (regular M1 processor) but on my laptop, I'm unable to connect. Does anyone have a similar issue?

Thanks @ybaransky, but I'm actually trying to use the USB serial connection. WiFi seems to work but I won't be able to trust it. Anyone with similar experience? 

@Miroslav Bakoš unfortunately the M1 Air is not mine :(

WG - personally, I always use a wired connection when I'm doing hard-core photography. Wireless seems like a great tool for casual use - visual, out-reach... Lightweight, little equipment, few cables running around. But if I'm taking a multi-hour photographic run, fully guided, controlling focus and filters, long exposures... - then I'd like the intelligence that runs all that to be wired in, with a vanishingly small chance of interruption. Going to need it anyway for the camera(s). It can be a PC near the mount, or an on-mount device (Raspberry-PI device, NUC...) - and then move the wireless to the other side of that intelligence, for perhaps remote monitoring and control - but interference in the signal wont fundamentally affect the task.

For me, brightline: When ES can functionally do everything I want in a session, WiFi it is. I'm firing up ASCOM or INDI - wired, never WiFi.

Well, I 100% agree about the wired connection but the issue I'm trying to resolve is IT DOESN'T WORK with my hardware. :(

My apologies - I misunderstood. I'll defer to someone using a MAC (I'm mostly a Windows user.)

Two generic things need to be configured correctly for all computers, and are a common source of initial problems making serial connections:

1) Your OS needs to have the correct "serial" port settings for this virtual-serial connection: 115200 baud, 8 data bits, no Parity,1 Stop bit, no Flow Control.

2) Your FTDI-chip USB/Serial cable may need to be programmed to flip a specific signal line. For Windows systems, the cable's default is fine - but some operating systems e.g. ASIAir, handle this signal differently. The chip in the cable can be programmed to accommodate these variations. There is a free utility available under Windows to re-program an FTDI cable - I don't know what its equivalent is for a MAC, nor if the MAC needs the change.

Make sure #1 is correct first. If it is, you should consider #2 next, but someone else will have to give you the "MAC" specifics.

The iExos 100 uses a USB cable with no chip.
