Why doesnt Picaxe have UART?

I am using the Picaxe 28x1 chip and I noticed, there is no UART for my bluetooth, why dont the picaxe chips have UART? All of the competitors do, and the only thing stopping me from switching over is the programming languange.... I dont want to have to learn C but I must eventually, so I have bought an ATmega 8.

UART in 28X1 PICAXE

Have a look at the PIC datasheet for the 28X1/40X1 at page 151
description there for the:
"Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART)"

For the 28X1, physical pins 17 (TX) and 18 (RX) as used by the HSERIN and HSEROUT commands

HSERIN:
Function:
Serial input via the hardware serial input pin (format 8 data, no parity, 1 stop).
Information:
The hserin command is used to receive serial data from the fixed hardware serial
input pin of the microcontroller.

HSEROUT:
Function:
Transmit serial data via the hardware serial output pin (8 data bits, no parity, 1
stop bit).
Information:
The hserout command is used to transmit serial data from the fixed hardware
serial output pin of the microcontroller.

I guess you must have overlooked a bunch of pages in the Basic manual ;)

Look for serin/serout, sertxd/serrxd, as well as hserin/hserout.
