I don't know what version of dosemu
you have there but I guess its one of
those 1.0.x which require root for using
serial ports. In this case just update your
dosemu.

To my great surprise dosemu used the serial port
when invoked as root.

Even though the permissions of /dev/ttyS1 etc are root/tty
and the user is a member of tty group.

I'm using dosemu 1.0.2 which is the latest I found
on the dosemu website.

What is the latest version and where do I find it?

Thank you,

A followup on the work-around I have found.

I use dosemu as user lba.
Changed permissions of /dev/modem and /dev/ttyS1 from root:tty to lba:tty.
Changed permissions of /dev/fd0 from root:tty to lba:users.

Now both the serial port / modem and floppy work when I start dosemu as user lba.
It looks like dosemu is looking only at the owner and not the group for deciding permissions.

Is this well known or should I report it somewhere?

I've also found a patch from 1.02 to 1.0.2.1 but no changelog to see what it fixed.
There is no indication in the 1.0.2.1.tgz file of what was changed either other than perhaps
comparing the source - that's beyond my expertise.
Is there a changelog anywhere I can look at?

Version 1.0.2.1

[Oscar A. Valdez]

It seems version 1.0.2.1 is able to correctly parse /proc/cpuinfo for
Pentium 4 processors. I'm not sure it includes other significant changes
from 1.0.2.0.

So for practical purposes, the latest stable versions are 1.0.2.0 and
1.0.2.1
