OK: You're right:
Short pins 8 & 9 to inform the VS that the console I/O is done through
the serial (printer) port.
Then connect pin 3 to pin 3 in the PC RS232. (DB9)
pin 2 to pin 2 in the PC RS232. (DB9).
pin 5 to pin 5 in the PC RS232. (DB9).
This should work.
If you plan to connect it to the PC's D25 RS232, wire as follows:
VS2000 pin 3 to PC's PIN 2
pin 2 to PC's PIN 3
pin 5 to PC's PIN 7
I've also shorted CTS-RTS and DSR-DTR lines in the PC side.
You'll find the pinout of a standard RS232 in the HELPPC program (free)
or in any MSDOS 6.x using HELP-INTERLNK-Notes.
I use Telix 3.22 Shareware terminal emulation program.
Serial port parameters:
9600 bauds (in fact VS2000 will auto-detect)
N No parity.
8 8 data bits.
1 1 stop bit.
If anybody in the list finds any mistake in this, please correct it.
Thanks.
