I’ve spent the last few weeks laid up with knee surgery. In that time I’ve revisited some hobby stuff including WorldBankBBS. Testing with Synchterm normally goes well, but when testing at 2400 baud it’s not entirely accurate.
The solution is to use WinVICE (the Versatile Commodore Emulator) to actually emulate a Commodore 64 connecting to the BBS. To make that work, you need another program called TCPSER. This program is a GNU/Linux native app and requires Cygwin to run on Windows. There is a Java port called TCPSER4J, and it works fine, but you get all of the problems of having Java installed on your system.
One of the things that is a big bonus of porting TCPSER4J to C# is that it allows the application to be run as a Windows Service which ensures you always have it running.
