Serial Port Issue with FC3 and dosemu 1.3.3
Hello.

Have serial port issues now that I didn't have before.
Please open the bug-report at an SF tracker, and attach the full -D9+s log to it, compressed with bzip2. If you can attach also the log of the good-working session - even better. If you can attach your program for testings - yet better.

Have the sudoers working.
You shouldn't. Please don't run dosemu with the root privs (at least for the bug-report).

It appears the problem only occurs after upgrading FC3 at some point.
In this case you should try the fresh kernel, not the RH-patched one. Although, from your log snip, this doesn't look kernel-related to me.

save space. The error seems to be here:
SER0: Interrupt 12 (1) cannot be requested: enable=0 IER=0x0
The DOS program haven't enabled the serport interrupts. There is nothing wrong with this, it can do that later, or it can use polling. Or maybe something isn't good with your program? Have you tried it in the pure DOS recently to make sure it still works? (eg, some configuration was changed and you haven't noticed)
