- INTRODUCTION
- COMDRIVE is a device driver which allows a PC to share its disk drives with
- another PC via the serial port. COMDRIVE works on the background, allowing
- system #1 to access system #2's disk drives while system #2 is performing
- other tasks (and visa versa). This process is "peer to peer"; each system can
- access the other's disk drives. To prevent potential File Allocation Table
- (FAT) mishaps, the remote drive in either case cannot be written to.
-
- INSTALLATION
- This driver uses a "null modem" cable, commonly available from computer
- supply dealers. Unless you have a lot of spare time and parts, don't
- bother making one. If you must, this driver requires TX, RX, and GND. If
- you don't know what that means, head to Egghead's (not an endorsement) and
- pick up a preassembled, professionally made tested cable.
-
- ** IMPORTANT **
- *** Because Microsoft eliminated the 32MB barrier starting with DOS V4.0, ***
- *** MAKE SURE BOTH SYSTEMS USE DOS VERSION 4.0 OR ABOVE, or BOTH use DOS ***
- *** versions LESS than 4.0. DO NOT MIX DOS <4.0 with DOS >4.0. ***
-
- Copy COMDRIVE.SYS and SEL.COM to the DOS directory on both systems. Assuming
- they are placed in the C:\DOS directory, add the following line to
- both CONFIG.SYSes:
-
- DEVICE=C:\DOS\COMDRIVE.SYS 1
- (this is for COM1; change the '1' to a '2' for COM2).
- To activate the drivers, reboot the systems.
-
- OPERATION
- To select one of the remote drives, type "SEL <D>" where <D> is the drive
- you desire. For example, to select the remote system's C: drive, type:
- SEL C
-
- For floppy drives, the disk must be accessed first by the system that
- physically houses the drive. This will allow DOS to determine the media type.
-
- The remote's drive can be used just like any other drive in your system,
- except it cannot be written to. It is normal to see the DOS error message
- "Write protect error writing drive X:".
-
- When accessing a remote drive, a small "REMOTE" window appears in the upper
- right corner of the screen of the remote system (only in text mode).
