[arm-allstar] RPI serial and dosbox

[Derek Chauran]

Hello, I'm building a repeater with a pi zero 2w, and I'm trying to program my radios (icom F420S) with the built in serial UART pins on the pi from dosbox (dues to lack of USB ports). I can access the serial from term95, and using the same settings as the radio (9600 8n1) and a jumper across rxd and txd I can send and receive data no problem, however the csf300s software says it is not getting a response from the radio. Further complicating matters is icom's love of 1 wire serial. That said, I have built adapters that work on these radios using 3v3  ch340 and ftdi adapters, and I use dosbox on my pc to program them, and I am using the same circuit.

I know that hamvoip has some ftdi specific modifications in dosbox pertaining to serial. Is there anything that would interfere with normal serial operation? Is there any way to get better debug information out of dosbox? Is there anything that would prevent me from grabbing the stock dosbox from arch-arm and running it?

Thanks,
