[wplug] Serial Comm.

[Weber, Larry A]

Anyone doing serial communications with Linux & POSIX?

I need to transmit raw 8-bit data bytes and the POSIX handlers are catching
and stripping out several characters from my "messages", 0x0d (CR), 0x11 and
0x13 (Xon, Xoff).  

I can change the Xon and Xoff characters to another 8-bit value but that
would only move the problem.  I have no idea how to get a 0x0d through the
comm link.

At this point I am not sure if the system refuses to Tx the characters or if
the receiver is stripping them.  I will get ahold of an analyzer on Monday
to find out which end is the problem.

Any one know of a good ref book on serial comm. with Linux?  The paper on
the web titled "Serial Programming Guide for POSIX Operating Systems" is of
no help.  Perhaps a non-POSIX solution?
