Ghostlink
Ghostlink v1.02 Beta 02/05/94 Copyright Bitz 1994
What is ghostlink:
Ghostlink is a link between an Atari GEM Computer (Master) and a MS-DOS computer (Slave) It allows the drives (floppy, harddisk, CD-ROM) installed on the slave to be used by the master as a GEM-partition. It is possible to connect up to 3 PC slaves (on different ports!)
So, you can, for instance, import a picture stored on a CD-Rom (connected to a MS-DOS PC) into Calamus!
Connection:
A simple nullmodem cable is required.
Installation on ATARI:
Run the program STMASTER.PRG
1. Select port & speed
On the left you see 3 channel boxes.
Set the wanted port and speed for channel 1:
- STANDARD All Atari's (ST/STE/TT/Falcon)
- The standard TOS routines are used.
- Select port & speed in the control panel. (Select 8 bit, 1 stopbit, no parity, no flowcontrol)
- SERIAL 2 Only MEGA STE & TT
- Speed: 300/600/1200/2400/4800/9600/19200/38400/57600/115200
- On a MEGA STE, do not use more than 57600 Baud
- MODEM 2 Only MEGA STE & TT
- Speed: 300/600/1200/2400/4800/9600/19200/38400/76800/153600
- On a MEGA STE, do not use more than 57600 Baud
- MODEM Only Falcon
- Speed: 300/600/1200/2400/4800/9600/19200/38400/57600/115200
2. Select the partition ID's
On the right side is the partition box. Double click on existing entries to edit them, or click on ADD to add an entry.
Editing a partition entry:
- Select a local drive ID (this is the drive-letter used by GEM to access the slave).
- Select a remote drive ID (this is the drive-letter used on the slave computer).
- Here you can also select "All existing drives"; this means that with 1 local drive-ID, you can access all the remote drives (the remote drives are showed as folders in the ROOT directory).
- Select a channel (take 1).
3. Click on Save to save the settings, this will avoid you to select
all settings every time the program is runned.
(Note: the settings are saved directly into the program!)
4. Click on install. The program will quit but remains resident.
Just install the icon(s) for the LOCAL partitions on the desktop.
The program can also be installed in the AUTO-folder, this way the dialog does not appear (select & save settings before).
Installation on MS-DOS:
Run the program PCSLAVE.EXE
- Select the port with keys <1> = COM1 <2> = COM2
- Select the speed with the function keys 1->10
300 -> 115200 Baud- Of course, the speed must be the same as the master speed!
- So, thats all, as long as the slave is active, you'll have access to it from the master.
- To quit, press escape (access is terminated).
Use:
Use it the first time at low speed, to avoid speed problems.
The data that is transfered is CRC32 controlled, so when a datablock send by master or slave has errors, it is send again (this as much as needed). So, if a computer is to slow, or in other words the transfer speed is to high, the system will lock up. In that case hold CONTROL/SHIFT/ALTERNATE on the master (Atari) and the transfer will stop with an ERROR code.
If on the MS-DOS screen, command tracing is ON, you can watch all used GEM-DOS operations (very interesting). Here you also can see the errors. MASTER ERROR means the master recieved a datablock with checksum error (Master to slow?) and SLAVE ERROR means the slave received a bad data block (Slave to slow?).
Notes:
What does not work:
- Renaming a folder on the slave. (difficult to do under DOS)
- Starting a program (.PRG of course) on the slave. (maybe in the next version...)
What's next:
- An Atari Slave program, to connect Atari to Atari
- More ports support (midi, parallell) (I am really curious to see the parallell speed...)
