[Amforth-devel] Amforth(9600), ZTerm(19200) why?

[avr f. <avr...@gm...>]

Hello.

I just got it working. But I can't understand one thing.

Why do I need faster baud rate in ZTerm compared to Amforth baud rate
settings?

When Amforth it set to 9600 and ZTerm to 19200. It works. why?

I just got my Arduino this week. So I'm learning..

Background: This is how I got it working
Tools: Mac, VMware Fusion, Studio4.14(589) in WindowsXP, ZTerm on mac

Amforth
1. Get amforth compiling clean. (change temp6->zl and temp7->zh)
2. Change ADCaddr -> ADCCaddr
3. Comment out r30 and r31 in macros.asm.
3. Set Baud rate = 9600
4. Change .include to device/atmega168.asm
5. Compile, f7.

Uploading hex and eep files.
1. Arduino have a extern crystal. (CKSEL=1111,SUT=00)
2. LFUSE=0xCF, HFUSE=0xDF, EFUSE=0xF8 (
http://palmavr.sourceforge.net/cgi-bin/fc.cgi)
3. LockBit=0xCF

Connecting with ZTerm
1. Connect USB cable direct to Arduino
2. Disconnect AVRISP mkII from Arduino
3. ZTerm 19200N81, no local echo, no Xon/Xoff, no Hardware handshake
   vt100, ZModem protocol for send and receive.
