Internal virtual modem doesn't seem to show DCD status #74

Hi:

I think the addition of the virtual modem is a great option. Nice sound effects, also. With this addition, I feel even more like I'm going on-line with a modem.

One question I have, and I may just not have the .ini set right, is in regard to the carrier detect (DCD) status.

I use Telix, and, when I am connected to a remote host, the status shows off-line, even after the remote system answers.

I am ok with this, but, just curious if it's a bug or a limitation in the modem code.

Thanks!

Hi, I've tested mostly with Telix myself and noticed this anomaly, but it seemed to work fine otherwise. The DCD line should be asserted appropriately and there's no option in the ini file to change its behaviour. I'll try to test with other terminal programs and see if it's something specific to Telix and its configuration.
