UART 1200 baud 8 bit no parity

Transmitted Data "D" + chr 13

HP48SX Sn. 3102Sxxxxx HP48GX Sn. 3422Sxxxxx
48SX UART 48GX UART
Emu48 Hyperterminal 1200,N,8,1
Emu48 UART Hyperterminal UART

We can see that the real HP48 calculators and Emu48 are using 2 stop bits behind the "D" character. For comparison I added a Hyperterminal dump with 1 stop bit.
