PCGET/PCPUT on the 5MB HDSK03.DSK: Mike Douglas' 88-HDSK CP/M

[Walt Perko]

Hi, 

I wanted to transfer some DZMBASIC files to a blanked HDSK04.DSK 5MB.dsk but the PCGET doesn't seem to receive the file from TeraTerm XMODEM/SEND ???  

TeraTerm XMODEM/SEND/RECEIVE works on other computers, just not the PCGET on my 0 drive on the Altair-Duino Pro.

Are you still running at 115K? You need to use 9600bps when doing XMODEM transfers. The CPU can't do much more than 9600, and the serial ports do not have a buffer or flow control. 

(Actually, there is a buffer - but the emulator just ignores it and sucks in data whenever it's there. I've been meaning to fix that on my fork of the firmware.)

Hi, 

Thanks Tom ... I throttled the USB port down to 9600 BAUD ... Now my default TeraTerm can stay at 9600 BAUD too.  

I don't see any difference in the speed of using the Altair-Duino Pro.
