Hey Guys,
So I am working with a VB6 project that is really old. This is my first time seeing this and it appears to be having problems when used with newer machines or with a usb to serial adapter. The purpose of the program is to load a script on the the chip?
It has to settings- send settings I assume, it is under the loadloader function
and here is the second set of settings that I believe is recieving, though I could be wrong. This is under the OpenComm function
When debugging , I noticed that it gets stuck in a look because the right .CommEvent isnt triggered. The program is continually looking for this.
However the only commevents that occur are
comEvCD 5 Change in Carrier Detect line.
comEvDSR 4 Change in Data Set Ready line. This event is only fired when DSR changes from 1 to 0.
and I have no idea what they mean, I tried doing some goggling but that has proven to be of no use. Could someone explain in lamans terms what those mean? Also any suggestions on what could be the problem here would be awesome.
I have also attached the settings of the serial to usb converter I am currently using.
