I'm happy to say that the above patch allows Foxpro/Dosemu file locks to be recognized by Samba 2.2.4. This means I can run the Foxpro application via Dosemu and under MSDOS/Win98/Samba simultaneously! The only issue I had with the above patch is that the line numbers did not match my version of Dosemu 1.1.3.2 with keyboard patches. I had to insert the lines manually. Now onto stress testing to ensure the changes do not affect Dosemu stability. Thanks Sergey!
