being testing "BCOS_0.05.IMA" in
http://www.asmhackers.net/LOL/BCOS_0.05.zipI only tested in QEMU so far. There's not much to report since there aren't that many command (only help, version, about, dump and reboot). All commands worked fine, but it looks to have typing issues.
When typing fast enough, it looks like some characters are randomly dropped.
I don't know how frequently you issue "getc" in your shell code, but that might worth the effort to have a larger input buffer ...
Btw, how did you like my cat #4 ?
