[arm-allstar] RPI serial and dosbox

[Derek Chauran]

Thanks! I don't have a spare usb port on the zero, but I'll pull out the fob temporarily and try my working USB adapters (ftdi and ch340). I suppose I could put one of my full size PIs in there, but I had other plans that are more difficult to accomplish with USB (transistor switching the port between radios).

Have you by any chance tried getting dosbox-x to build? I gave it a shot but can't get it to compile successfully on the hamvoip image or any pi for that matter. I believe it has better debug capabilities.

Derek,

I think the HamVoIP version of DOSBox should work fine as-is to program
the F420S radios, etc.  By far the simplest solution is to buy an Icom USB
programming cable and use that to setup the radios.  I think all my icom
cables used clone prolific PL2303 chips, which work okay with Linux.

The FTDI hacks in HamVoIP won't interfere.

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.

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?
