Hello:

	I am developing a serial communications facility in Borland C++ 
under MS-DOS.

	Under the scheme of multiple interrupts, where an interrupt 
generated by COM2 is interrupted by COM1, can any programmer verify through 
experience if the Borland C++ compiler generates code which is re-entrant 
(subsequently preserving the state prior to any interruption).

	Direct e-mail to 'mbrown@trentu.ca' with suggestions would be 
greatly appreciated.

Thanks 

- Martin.
