In a multitasking system you cannot use software timing in any case, because
the timing loop may be interrupted by the task switch.
(Not even counting normal interrupts).
The exception is i2c protocol, it does not care a lot if you wait a while
before the next bit.
On serial better is to use a micro (cheap 2 $ PIC has serial port).
Par port is more complicated, but simple 4 bit read / 8 bit write
bidirectional with a micro is possible (else ECP etc).
These soft loop systems worked fine on MS DOS / DR DOS though, even had
a CB packet terminal program on a serial port in DOS.
As to upgrade to > win 98, I use dual boot Linux / win98, with as default
Linux, why sell yourself out to Bill Gates?
They sort of want control over you, your programs, the sites you visit, and
of cause your purse.
Not a day goes by without a new MS Windows virus warning, I have been with
Linux from SLS kernel 0.98 or so... and NEVER had ANYTHING that did any harm
how many years - let's see, just grabbed the old SLS disk 4
-rwxr-xr-x 1 root root 181475 Aug 3 1993 shadow.tgz -
So, that is almost 11 years, and NO attacks have succeeded in that time.
Recently I have been doing some deeper study of ipchains, the Linux packet
filtering, as I will be online 24/7 since ADSL is coming here this month
Very cool stuff, you have complete control over all traffic, with just a few
simple commands, easily scriptable.
No bloat, no constant 'security patches' needed, just simple to the point
good old programming.
Linux rocks, MS sucks.
