[Flashforth-devel] USB, flow-control, and linux

[Mark G. <bit...@gm...>]

Hello everyone,

I am trying to run flashforth latest from GIT (appears to be 5.0, git
commit 304e4cc23851c7ff5bd6360f4c8c16b880a0d51c)

I have an old USB BitWhacker board (v1) with an 18f2550 on it, 20MHz crystal.

I have made the adjustments to the frequency and divider to get USB
working, however when I connect via /dev/ttyACM0, it appears to send
some, but not all of the characters in the tx buffer.  If I hit enter
a couple of times, or cause enough traffic, another chunk of the
txbuffer comes down.

I have setting hardware flow control, disabling idle_mode, and a
couple of other things, but I don't seem to get proper expected
behavior.

Are there other things I should be doing to enable USB besides
defining USB_CDC when assembling?

I have tried searching the archives, but I didn't come up with anything.
