Before ASCII was a standard, there was "EIA". It is a totally different code, although the translation is pretty straightforward. The EIA code is also known as RS-244. Bit 4 (code value 16) is the parity bit, right in the middle of the 7-bit byte. Here's one doc that shows the code, although I found it a bit hard to read http://faculty.etsu.edu/hemphill/entc3710/nc-prog/nc-04-01.htm
The PC ought to be able to read and send the files as raw characters (probably should set for 7 bits, no parity). You would then need some converter programs to make them readable. Possibly, the Yasnac controls can be set to send with ASCII format.
