Problem with reading offset 0x034E

[Dominik]

Hello, I'm trying to read the offset 0x034E - COM1 frequency, using lua, Here is the code

while 1 do
file = io.open("test.txt", "w")

ppp = ipc.readUW(0x034E)

file:write(ppp, "\n")

file:close()

ipc.sleep(50)
end

The loop writes the value of this offset to the file. The value of this offset is 6194, com1 frequency is set to 118.050 

It reads this value wrong and I don't know where I went wrong. Please help.

Dominik.

I think I found a solution to the problem, I have to use

string.format("%04X", value)

Yes - the offset is in BCD format, so you need to look at the hex representation, as it says in the offset status documentation:

COM1 frequency, 4 digits in BCD format. A frequency of 123.45 is represented by 0x2345. The leading 1 is assumed.
