brill:
Is it possible to override the baud rate in these tools?
I always wonder how fast the port can go, but I lack the time to setup all the required stuff.

rama3, if you enter cheat code:
D00748AA-1040
800748AA-1000

yor can disable bps check for NETYAROZE loader
i'm trying force speed up to 230400bps (freeze) & 921600bps (freeze)
115200 - MAX BPS for Siocons software
1 x SCPH-1002, 1 x SCPH-7502, 1 x SCPH-102
1 x Xplorer V2 with Caetla [v.0.37]

Okay, did you also check some lower speeds?
The sending and receiving side need to use the same baud rate, and trying out a lower speed can test if that works.

Thanks for testing! :)
Well, that's thoroughly disappointing though. It starts to look like a real hardware (or maybe Kernel?) limitation.
Still have the big guns in reserve of course (hardware mods and BIOS patches) :p

I patched PSXSERIAL (PS and PC parts) at 256,000 bps and it works at this speed well.

some measurments

HITPSX.EXE 1574912 bytes long

Loading time at 115200bps - ~02m:20s
Loading time at 256000bps - ~01m:05s

speedup more than 2 times

Huh, when I did tests with my own loader at more than 115200 baud I got receiving issues on the PSX side and would frequently miss bytes. I'll have to take a look into it again I suppose.

Can you open a new thread? This one's going a bit off topic as it's supposed to be about building the cable..

It could be worth looking at the feasibility of patching siocons to run at different speeds or posisbly even modifying the gave save on the memory card to see if different speeds could be achieved?
