The time taken to program a 16F877 (not the 'A' revision) is dominated by the
4mS/word  program write time and not the comms overhead.

On the proviso that the programmer is using the hardware UART with a ISR and
FIFO the only difference between 57600 and 19200 baud will be the slower
read/verify. This is around 6-7 seconds as measured with the WARP-13
software and a range of programmers I have modified to work with standard
baud rates  from 19200  up to 115200 baud. (Approximate times were 42 and 48
seconds for a full program and single pass verify @ 19200 @ 57600
respectively.
The difference is hardly "quite lengthy" in relative terms.)
