[GreenKeys] Model 15 + C-64 Baud rate question

[drlegendre .]

Thinking about trying to use a C-64 to communicate with a model 15 that
should be arriving in a couple of months. The native RS-232 routine on the
Commodore has a minimum baud rate of 50, whereas the 15 wants 45.45 or so
I've heard.

Will the 15 tolerate 50 baud? FWIW the C-64 routine sets a pair of 256-byte
FIFO I/O buffers for RS-232 communications, not sure how that might come
into play.

If it can't take continuous data at 50 baud, what if I only send one
character at a time, with a slight delay such that the total CPM doesn't
exceed the max char rate of 50 baud? IOW, can it take one character's worth
of bits a little faster, so long as the next character doesn't arrive too
soon?

Thanks for any input.
