Another geek (MUCH more advanced than I!) whipped up a nice little EXE file that syncs the DOS clock to the Windows system clock. It's not NTP, itself, but Windows calls an NTP to sync itself so this utility gets accurate time. One of the BAT files calls the EXE and exits back to the GWBASIC program …

Just for the sake of those that have followed this thread, the looping BAT files did, indeed, do the trick. It's been running flawlessly for months, now. 😀 (Not counting the fact that Windows, itself, gets stupid and needs a reboot about once a month.)

In case anyone is curious... that did the trick! :) Even if the clock drifts a few seconds by the end of the day, that's not too serious. The midnight re-sync has been working all week. The looping BAT files also have the added advantage of re-launching the program, if it's accidentally closed. ( …

I think I found a solution! With some clever use of loops in a BAT file, I can make the program drop to DOS at midnight, where the looping batch re-launches DOSBOX, thus re-syncing the system clock. I will leave it running for a few days this way, and see how well it holds up. :) Re-writing the code …

Well.... unfortunately, QB64 doesn't support the important COM(x) port functions that I need! Sigh. :( SO FAR, the issue is either the serial works or the clock works. They are thus far mutually exclusive, due to limitations in the BASIC emulation software I've tried! Sigh.... :( The thought of …

If QBASIC will run this program, that could make it possible... but this is a 32 bit system. What is "SVN"? 😀

Bummer. Oh well, thanks.

Ok... can you point me to a site where I could get that? 😀 I even tried PC-BASIC 3.23, but that didn't work, either. It "times out" when trying to access the COM1 port, just like it does in DOSBOX.

Hello, Forum! This is my first post. I'm trying to run a GWBASIC program that relies upon the TIME$ and DATE$ variables working. It's running on a P4, 1.5Ghz machine with 768 megs of RAM and Windows XP/SP3. I'm using DOSBOX .74 The BASIC program is communicating via the serial port as desired, so …
