Here are a few tips on getting VICE for Linux configured in such a way that you can connect to CommodoreServer's V-1541 virtual disk drive service. For this, I am using the VICE for Linux and the x64sc binary file, version 3.4 SDL2.

1) From the Configuration Menu (F12), select Machine Settings:

2) Then, under the Hardware Expansion section, select RS232 Settings:

3) Under the RS232 Setting section, activate the Userport RS232 Emulation option, and change the host device option to 3. Then, under the Host Settings section, put the IP address 50.112.163.22:1541 on the Device 3 line and ensure the Baud Rate is set to 2400.

Now, load up the V-1541 configuration program and log-in as described in the CommodoreServer documentation, and all should be good.
