PPS10

Some time ago I've bought Vellemans pocket scope PPS10, it's nice tool with serial data out but it lack linux support so I've started to work on this issue.

Here is pinout of the original pps10 cable:

So that RxD, TxD, and RTS are connected.
Okay it looks like there is optocoupler powered from the serial cable (from the TxD and RTS) and just because of this it doesn't work with usb<->serial cables and seems to lost some bits on new PCs. Quick solution is to create your own cable with external power. For most PCs I have just adding small capacitor about 1-10uF seems to fix most of the losts.

Seriall setting according to the manual are:

baud rate 57600
data bits 8
parity no
stop bits 1
handshaking no
