Hi,
For long long time, I detached TX382B based UART board and
recently I reinstalled it.
John Kelly's report "TXIC TX382B UART controller support"
(https://marc.info/?l=openbsd-tech&m=147352668517825) says this controller
sometimes lacks THRE interrupt, I found the symptom.
I'm not an OpenBSD user, I'm not asking for help. I'm posting here

marked as PCI 60806 instead of TX382B. I never found a data sheet for
it, but after some trial an

Recently I bought a cheap PCIe UART adapter.
It uses ASMedia ASM1083 PCIe-PCI bridge and TXIC TX382B UART controller.
There is no details/datasheets about TX382B, but a Chinese seller
saids that it is similar to WCH351Q (aka WinChipHead's CH351Q). [1]
So I add new entry to pucdata.c like C
Hello,
The diff is committed (ok by deraadt@), and I am testing the behavior of
TX382B's FIFO.
