This may be of interest to those who are running VICE to emulate a Commodore 64 and using tcpser to bridge serial I/O to the internet:

There seems to be an isssue with how tcpser encodes the carrier status (see post from lemon64.com below), affecting serial file transfers.

I have tried a few of the many forks of tcpser (including the fozztexx one and Jim Brain's original code) and none of them worked when trying to transfer files.

Discussion: https://www.lemon64.com/forum/viewtopic.php?t=72228#top

The solution to the problem was to use a different tool to "bridge" the serial communication: TCPSerial.jar which is a Java based implementation of tcpser. It is an updated version of Jim Brain's Java codebase (tcpser4j) to work with Java 21:

https://github.com/MyDeveloperThoughts/tcpserial/releases/tag/Version1.00

Using this tool instead of the original, C code based tcpser made it possible to finally transfer files using x/ymodem.

I thought I should let you know ... 🤔

First attempt at a convoluted "teletype" connection to @particlesbbs

Thwarted by a busy signal but I will try later :)

Using a USB-to-Serial cable, a #nullModem, a 9-to-25-pin adapter, #tcpser running on Linux, and a Brother EP-44 #typewriter

This will likely be of interest to very, very few people, but I put together a tcpser-related Python script:
https://github.com/Kirkman/tcpser-trace-convert

Basically it converts captured trace data into a text file.

I used it to capture the "Instant Graphics and Sound" output from my BBS. (My IGS stuff is partially generated by JS, so that's why I needed to capture it from the "modem" while connected).
