sets up UART0 to do both RTS and CTS `wait_ESP32` now does a pure wait, with no timeout, as an Agon can’t operate without a working VDP, and the VDP hasn’t supported the lower baud rate in forever. it will call the “general poll” command sending a value of 2, which will trigger a compliant VDP to switch to full duplex from experimentation it seems that MOS doesn’t actually really need to care whether the VDP _actually_ switches over to full-duplex mode or not - it will carry on working regardless includes a fix to `UART1_serial_GETCH` which was looking at the incorrect flag bit to determine if UART1 was connected - it was looking at the bit for UART0 so would always find a connection based on a PR to Quark by S0urceror, but with a few additional changes

wait_ESP32now does a pure wait, with no timeout, as an Agon can’t operate without a working VDP, and the VDP hasn’t supported the lower baud rate in forever.on successful receipt of a “general poll” response it now sends a "set feature flag" command to switch the VDP to use full duplex comms
from experimentation it seems that MOS doesn’t actually really need to care whether the VDP actually switches over to full-duplex mode or not - it will carry on working regardless, therefore no checking is done to verify the switch has happened
