I received my null modem cable setup and tried to establish a working connection between my 486 laptop with 9-pin serial interface and my Sol-20 serial interface, but have failed. My 486 Laptop is an HP Internet advisor workstation. Back a few years ago buying one of these was a cheap way of getting a vintage PC laptop with a 3.5” disk drive. I’ve just it successfully to create 720k disks for my vintage HP computers. This PC has many interface ports along with the 9-pin serial interface. It is running Windows 95. I’m not really sure which COM port (COM1, COM2, COM3, etc) the 9-pin aerial port is. I’ve tried them all. I am using Hyperterminal and set the data rate for 1200 and 8-N-1. On my Sol-29 I have entered the SET I=1 command, but when I try to send over the ‘train.ent’ file. Nothing happens. Is there a way to check if I have the COM port number correct on my PC? Also, does anyone have a detailed, step-by-step how-to instructions on how to send an ‘.ent’ file from a Windows PC to the Sol-20?
