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.

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)
