my cust is reporting poor ‘upload’ speeds when they send cnc programs via rs232 from a win98 box running a dos based cam program in a windows dos shell (no dos mode. win98 se all patches.
we used the sample pif for msdos mode games to take a swing at a autoexec and config.sys file which we used both in the root menu of c and also tried it in the advanced dos mode config settings in the pif for the cam program. dos mode seems to work well but non dos mode seems to choke up and slow down…
they think it is working great in ms-dos mode. meaning fast serial like they expect. we need to test more to see, but that is how it is looking right now.
if we run the program in a dos shell or whatever you get when you make a shortcut to dos executable, comm seems to work but slowly.
the settings in the cam program appear to be 4800, 7,n,1 even, xon xoff. nothing has changed on the nc’s. we have changed the com settings in device manager to match.
