Serial port problem

[amiga_amigo]

Hello all,
i can't seem to get my serial connection with WinUAE 4.4.0 to work as it should - maybe someone can give me hint.
I need to send data to a piece of hardware using the following settings: baudrate 31250, 1 start bit, 8 data bits, parity even, 1 stop bit, no handshaking (not supported by hardware).
Everything works fine on windows but i can't get it to work from within WinUAE.
For debugging i've set up com0com (com1 <=> com2).

WinUAE IO-port settings:
com0com (com1) selected in Serial Port dropdown
Shared - unticked
RTS/CTS - unticked
Direct - unticked
uaeserial.device - unticked

WB serial preferences:
baudrate: 31250
input buffer size: 8192
Handshaking: none
Parity: even
Bits/char: 8
Stop Bits: 1
Applied "Use" and "Save"

echo "hello" >ser:

gives the following ascii output in a terminal on windows connected to com2:

A9,
68='h',
A8,
65='e',
A8,
6C='l',
A8,
6C='l',
A8,
6F='o',
A8,
0A='\n'

Tried various settings, none worked except if i switch to parity 'None'. Unfortunately this is not an option, since this setting is not supported by my hardware ('even', 'odd', 'mark', 'space' - all supported, but 'none' isn't).
What am i doing wrong? Is parity not supported / buggy? Any alternatives? I need to send data to the serial port from within the amiga shell...
Any help appreciated.

What odd hardware are you using that doesn't support parity = none?

[Toni Wilen]

uaeserial.device supports parity. (But probably was never tested..)

Paula serial port emulation can't because Paula serial port parity is Amiga-side serial.device software feature so there is no way for emulator to know if data written to SERDAT is actually 8/9 bits or 7/8+parity bit.

Thanks Toni,

so if i understand correctly, then sending data with parity is impossible from within WinUAE using serial.device due to this Paula thing?
Maybe using uaeserial.device? I read somewhere, that it's directly connected to PC-side comports (unit == portnumber).
Is it possible to use uaeserial.device from the shell (classic WBs 1.3 ... 3.1)? Is there a "compatible" handler to mount it e.g. as aux or whatever?
I'd like to use shell scripts to compile code and send the ouput via serial to the connected hardware.

Googled quite a bit for uaeserial.device but there's not much information...

uaeserial.device unit 0 is first PC port, 1 second and so on. Otherwise it works just like normal serial.device.

But I am not sure if all PC serial ports support 8 + 1 parity bit mode. 7+1 would have worked even with emulated serial.device because there is no hardware level difference between 7+1 and 8+0.

I think there was some way to customize serial device name and unit to AUX handler via extra mount list entries but I don't remember it now. Or just hex edit l:aux-handler
