First post, by polsimp
I just purchased a used police scanner with an aftermarket serial port interface. I want to ensure the computer is communicating with the serial port and Dosbox before I fork out $40 for the software to run the radio with the computer. It is a newer computer (core i7), but it has a real RS232 because it was originally a business computer.
I found this thread before making a new post:
I changed dosbox.conf to "serial1=directserial realport:ttyS0", but I'm getting error 9 just like the guy in the previously mentioned thread did. Just for good measure I did try "ttyUSB0" but still got an error. I also tried ""serial1=directserial realport:ttyS0 irq:4". I've been running Linux for 16 years but I'm still pretty green when it comes to using the terminal or anything similar. The following might help:
$ dmesg | grep tty
[ 0.110577] printk: console [tty0] enabled
[ 0.370421] 00:04: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[ 0.391961] 0000:00:16.3: ttyS4 at I/O 0x40a0 (irq = 17, base_baud = 115200) is a 16550A
Also if it helps the aftermarket interface is called the Optoscan 456. It is ancient and there is precious little information to be had regarding it's use. I tried asking in a radio forum but didn't get much help. I have managed to confirm that I am using the correct cable (straight through, not null modem).
