On manual 2, under the description for the sertxd command; there is the following sentence:
The baud rate is fixed at 4800,n,8,1
However on the next paragraph, there are the following paragraphs:
Increasing the clock speed increases the serial baud rate as shown below.
4MHz 8MHz 16MHz 32MHz 64MHz
4800 9600 19200 38400 76800
What I understand from this description, is that the baud rate is fixed to a submultiple of the clock speed, which means that if I'm running my 14M2 at 8Mhz, then sertxd will output 9600,n,8,1....this is completely clear to me.
What is also clear to me, if I want to upload data to my computer via the PE6's Serial Terminal, then I've to select the 9600 baud rate.
My question then is...............it was my understanding that the Picaxe's internal clock is not accurate enough for serial transmissions above 4800 baud, correct? I remember attempting to send data to a serial LCD display at 9600 baud, and I got garbled characters.
