I bought a serial port bracket (see attachment). After connecting it to the motherboard's COM2, the printer could not print normally. The printer prints normally on COM1. (Operating system: MSDOS)

Set in BIOS:

OnBoard Seriel Por1: Auto (Aoto/Disablled/3F8h/2F8h/3E8h/3E8h)
OnBoard Seriel Por2: Auto (Aoto/Disablled/3F8h/2F8h/3E8h/3E8h)
Serial Port2 mode: normal (Normal/IrDA/ASK-IR)

Do I need to set something?

I bought another one and it worked, maybe the original one had the wrong bridging!
