Hi!
Does anyone know if there is a real time library or kernel/BIOS
for 386-PC that interfaces to Turbo C++.
What we want to do is:
1. Keyboard I/O
2. Screen I/O
3. Disk I/O (if possible)
And always be able to respond to hardware interrupts (IRQ9-IRQ11)
within 5 micro seconds or about one hundred clock cycles.
That is: The I/O routines must be reentrant and never diable
interrupts more than a few micro seconds.
Best regards,
Jonas
PS. Please don't use reply! The return path is not correct!
Please send the letter directly to the internet address.
