I solved a similar problem by installing a conf-File for each user. The user
has to load DOSemu with "xdosemu -f $HOME/your_conf_file". In this conf-Files
I redirect the lock-Files to different directories. This is possible because
my DOS program reads from a card reading device at /dev/ttyS0 and uses it
only for a short time. Locking for me is not really necessary.
With this configuration I can read from the card reading device from several
DOSemu sessions. But it can take up to 3 efforts until the program has
retrieved the data.
Hope that helps
Claudia
