Good day. I created a C language application for RS-232 that transfers the file. I use the com0com emulator on Windows and work between two ports on Linux. On Windows, my application runs fine or 115200Bd, but on Linux, the cache overlaps even though the process of sending and receiving blocks is asleep. Have you not encountered such a situation?

Thank you sir.

Excellent video. I have attached a RS232 to USb and connected the unknown scientific equipment ( SD-100 Verity Monochromator circa 1999 Device) No software available to drive commands to the unit. I have randomly sent commands through the Debugging software to send commands and observe the received data. The unit does not respond and not sure if its because its looking for the right command etc. I am at a lost and would like to be able to use this equipment. If anyone has an idea or actually has the software please contact me here etc. Anyone who might hav an inkling on the approach or a better idea please let me know... Thanks in advance!!!
