Win NT, serial port COM1. I inherited this project because it doesn't work as is, so I'm completely in the dark.
When using CWSerial1 in VB6, I am getting -1002 (or 30301) timeout errors. This usually occurs when attempting to read data a second time. In Excel, I can't read even once. I'm even not sure my COM1 is configured properly -- using the hyperterminal test, I do not get double characters, using the paperclip loop on a cable I seem to be able only to send. But, I can't find anything else to change on the config. I have updated cwinstr.ocx to the most recent version. We have several instruments which use GPIB and the application works fine for them, but the same application toggled for serial and this instrument does not.
Any help is appreciated. I hope it is something obvious.
