Hello Joanne- Please excuse me for slipping in here. I assume from this
thread that you are still using a HardFrame controller. I have had mine
for several years and it has worked PERFECTLY in my unaccelerated A2000.
I just purchased a new Supra 14.4K V32bis modem and boy was I
surprised when I tried downloading at the fast speed. When ever my telecom
pgm (tried several using CTS/RTS handshaking) wrote to the HardFrame and
Quantum drive I got Zmodem CRC errors ;^(
I can get it to work if I set the MaxTransfer down from 130K to
1024!!! bytes; but that drops my HD disk speed from over 500K down to 100K
;^( Not acceptble; like driving your sports car all the time in 1st gear.
I noticed that GVP has a patch pgm for their Series II Scsi that auto
matically reduces the # of bytes transferred at one time when ever the
serial device and HD are active at the same time. How hard would it be to
write one for the HardFrame??
I hope I am not destined to buy a new Controller card, buy a 3rd party
serial card, downloading to ram: or floppy (yechh!!) or buying an
accelerator (Probably and excellent idea)
Any thoughts would be greatly appreciated. Thanks
