MS-DOS and MS-DOS Network Devices
PRO/5 is capable of opening devices maintained by MS-DOS Networks. Usually, these devices are the same as you might access in the command processor where you place "/dev/" at the start of the name and remove the trailing ":" character. (The colon is an invention of the command processor.)
Most MS-DOS systems do not have any protocol support on serial devices, so device drivers IBMCOM1.SYS, and IBMCOM2.SYS are supplied on one of the PRO/5 supplemental diskettes. These files are MS-DOS device drivers for the COM1 and COM2 serial ports on an IBM-PC or compatible system. To install either driver on your system, copy the file to the root directory of your boot disk and add the line to your config.sys file:
DEVICE=IBMCOM1.SYS (or "IBMCOM2.SYS")
When you reboot your system, the COM1 (or COM2) device will be setup as a XON/XOFF bi-directional buffered port.
The device drivers have the following defaults:
baud rate: |
9600 |
Word size: |
7 |
stop bits: |
1 |
parity: |
odd |
The default port settings may be modified with the MS-DOS "MODE" command. (See your MS-DOS manual for details.)
