just like old
db9DE-9 console cables. -
@jknott do you remember the DB-25 on the back of that us robotics modem that was used for out of band? You needed an adapter to connect to it with the Cisco rollover blue cable.

I only see an option to set the baud rate for serial communications.
You would see that if it's a serial console only install. What are you running on? What image did you install from?
-
@stephenw10 I am running the serial console image. As I mentioned I did get the serial console working in securecrt app, not in putty. That being said I don’t see any option to turn serial console on/off under the admin access page.
Anyways, my issue is resolved even if the toggle is missing.Another question though. Can a serial image install be set to use vga as primary output and vice versa? Is there a setting to control that. Let’s say I want to hook up a monitor and would like to use the vga output?
-
Yes, like I said on the serial only image there is no option to disable the serial console by default. Otherwise you could easily lock yourself out.
Try removing the file: /cf/conf/enableserial_force.
That should allow you see the console options. -

Yep, I have both a USR Courier modem and blue Cisco cable here. However, that DB-25 wasn't used for out of band, it was used for the data. Initially personal computers used DB-25 connectors, but switched to the DE-9 with the IBM AT.
BTW, my IMSAI 8080 had a bunch of holes punched in the back panel, for DB-25 connectors. I used 3 of 'em. Back in those days, I was also working with modems at customer sites.

Yep. That's what I have here. My pfSense box is connected to both my USB/HDMI KVM switch and can also connect via serial cable. It's been a couple of years since I set it up, so I don't recall the details, but the serial port definitely works. I had to use a gender bender cable to connect the computers, as they both have male connectors.
-
@jknott well in my case, I have serial image version of pfsense installed. I notice that on the vga output, the display stops updating at some point of the boot process, however I get the full output in the serial console till the boot is finished. Is that normal? That's why I was wondering if I could flip between serial vs vga as primary output modes?

-
That is normal if serial is set as the primary console.
No there is no force file for vga.

I've never seen that.
You mentioned it locks up in VGA. That might be a hardware issue.

@jknott The earliest computer I had was an At&t PC6300 it had a DB-9 for the keyboard, monochrome guy. I also remember my Tandy 102 my uncle got us one christmas had a DB25 on the back. My Dad had a Commodore 64 I never got to play with it. The thing was disconnected by the time I was able to. Again, the monitor was dead that went with it and it was outdated at that point but that guy had some connections on the back also. Today I have the C64 mini so I got to play with it in the end, Thank you Santa!!!
