You should send whatever format and bit rate the receiver requires.
See, here's the rub. The supplier who makes the device I'm testing says they only use 1 stop bit. However, when I read the bits off an oscilloscope, there is interbyte spacing of 1 period. To the scope, its indistinguishable from two stop bits. Should I config the serial to 8N2 just to be safe?
