ValueError: non-hexadecimal number found in fromhex() arg at position 15

[Robindeko]

Describe the bug

I've updated Python Can to 4.4.2 (not sure which version I was using before). All of a sudden I'm getting a "ValueError" exception in bus.recv() every few minutes.

For now, I've handled the exception and proceed to wait for the next message. it works, but now I miss an occasional packet from the CAN bus.

the exact message is: /can/interfaces/slcan.py", line 218, in _recv_internal ValueError: non-hexadecimal number found in fromhex() arg at position 15

the "position" always seems to be either 1 or 15 (havent seen any other numbers.

To Reproduce

the code I use is simple:

CanMessage = bus.recv(35)

Expected behavior

previous versions did not throw this error (ever)

Additional context

OS and version: Ubuntu 24.04 LTS Python version: 3.8.10 python-can version: 4.4.2 python-can interface/s (if applicable): SLCAN interface from TITAN (USB adapter) https://www.titan.tw/product/usb-can-m/
