Hardware / Re: Serial Port Shenanigans - ArcaOS 5.1.1 on a Lenovo M920t

I am a little confused by the vmodem vs physical modem stuff, but I have a very wild, shot in the dark, suggestion. Try switching on CSM AND limiting your system to a single processor and see if SIO will run. To limit to a single processor add /MAXCPU=1 to the ACPI.PSD line in CONFIG.SYS, e.g.
PSD = ACPI.PSD /MAXCPU=1
The reason I suggest this is the COM.SYS on my AOS 5.1 system is dated 8/3/2002 and SIO2K was released 6/6/2002, so they were both revised/released about the same time, suggesting that maybe the issue isn't in the COM stack/driver/interface but rather someplace else.
One processor should still be fast enough to handle multiple BBS "lines" - after all people were running multi-line BBS on machines before there were multi-core processor machines.
