Configuration of Prolific PL2303 USB — Serial adapter
Post by ki7ay » Thu Oct 08, 2015 10:55 pm
I have a Prolific USB to Serial adaptor and would like to be able to read and/or set the serial parameters. I have added the line to /etc/modules so the drivers load and the device is assigned to /ttyUSB0, but I’ve no clue how to read the settings. Also added myself to the dialup group.
Thanks guys. I want to use the adaptor for CAT and PTT on an FT-817nd radio so I can control it from FL-Digi (Hamspeak, sorry).
Thanks! Jim Darrough

Open source drivers are included in Linux kernels 2.6.11 and later. These have support for the Prolific 2303 chipset, and recognize the plug and play IDs of the Plugable adapter.
setserial is a program designed to set and/or report the configuration information associated with a serial port. This information includes what I/O port and IRQ a particular serial port is using, and whether or not the break key should be interpreted as the Secure Attention Key, and so on.

Имеется usb ttl переходник от фирмы cablexpert, и он категорически не хочет работать (в шЫнде хоть эхо дает, но потом вешает наглухо гипертерминал и putty). Вроде адекватно определяется:
