Custom baud rate code fails to build on mips*

[jcowgill]

Enabling USE_CUSTOM_BAUD in the Makefile and then building on MIPS fails with:

cc -Wall -g -DVERSION_STR=\"3.2a\" -DTTY_Q_SZ=0 -DHIGH_BAUD -DUSE_FLOCK -DHISTFILE=\".picocom_history\" -DLINENOISE -DUSE_CUSTOM_BAUD -o term.o -c term.c

On MIPS, glibc's copy of struct termios does not have any c_ispeed or c_ospeed fields.

As is clearly stated in the documentation, custom baudrate support is not available for all OS and architecture combinations. MIPS / Linux is obviously not one of them.

Naturally, any patch to fix this (and add support for MIPS/Linux) would be greatly appreciated.

I may try to add support myself at some point, but: (a) since MIPS libc does not have the c_ispeed and c_ospeed fields, the patch will not be totally trivial (requires some thought and work) (b) I don't have the hardware to test it on. Because of these, it would be preferable if someone better equipped would provide the patch...

For MIPS / Linux, the default picocom build (without forcing baudrate support) should work ok, (but without custom baudrate support)

Similar recent failure.
