There is no system call, but you can grunge around in the DOS data structures
to find out. Take a look at INT 21/AH=52h in INTER191.ZIP, now available
from
msdos.archive.umich.edu in /pub or /msdos/info
grape.ecs.clarkson.edu in /incoming/msdos
chyde.uwasa.fi in /pc/incoming
and soon (probably by the time you read this) from
wsmr-simtel20.army.mil in PD1:<MSDOS.INFO>
