Hello,
back again

Quick kludge to fix the Iconx: error messages.
1) Open a shell window (I normally press RAmiga E and type newshell)
2) Type the following:
copy sys:disk.info to sys:prefs/env-archive/sys/def_disk.info
copy sys:disk.info to sys:prefs/env-archive/sys/def_pc.info
3) In the shell type:
dir pc:
Do you see anything?
Right, you have a serial cable. You need to configure PC2Amiga correctly.
There is a config program in the PC2Am folder of the archive off Aminet, I know, I just run it! It is called ConfigPC2Amiga.
Select the serial port option and set the baud rate to 38400 for now.
Inside the PuttoPC directory are the programs for the PC.
Have you run the install program?
