Another "Is it just me, or what?" department.
While writing a simplistic program in Turbo Pascal v6.0 for MS-DOS that
basically just echos characters from the console to the comms port and
vice-versa, it became necessary to use the "alarm" interrupt - int 4Ah - found
in the IBM AT's BIOS.

After many hours of hair-tearing and fruitless debugging, I decided to test the
program under plain-vanilla DOS. "Aha!" says I. "The program _does_ work".

So, my question:
Does the OS/2 _virtulise_ the AT BIOS alarm interrupt? Can someone please check
that in fact interrupt 4Ah is triggered as advertised? - Under both a VDM and a
DOS5 boot from drive A the program failed to work as the interrupt never
triggered. 

The interrupt btw is _supposed_ to be triggered when the AT real-time clock
reaches a certain alarm-time value. The alarm-time value - in BCD H:M:S format
- is set by another BIOS interrupt whos number escapes me at the moment.

Is there a problem with OS/2's interpretation of certain BIOS functions? Can 
someone clear this up?
