[Ser2net-devel] chardelay not doing anything?

[Rogan D. <ro...@da...>]

Hi,

I am trying to interact with a Lithium Battery Management System,
accessible over RS232, using the BMS PACE protocol.

When reading over direct serial, the application
(https://github.com/tertiush/bmspace) works fine, but when going via
ser2net, it reads less than the expected number of bytes, and errors
out. Part of the problem is that the bmspace application simply does a
single read, and expects everything to be there. I have fixed this by
making bmspace keep reading until it sees the end of line character on
the TCP socket, so that is not a huge problem.

But it is my understanding that the chardelay group of options is
supposed to be able to address this as well, by making ser2net read
more into its buffer from the serial port before forwarding it to the
TCP gensio. However, setting `chardelay-min` and `chardelay-scale` had
absolutely no impact on the number of characters forwarded into the
TCP connection and read by bmspace's solitary read.

My configuration file is appended below. I did also try putting them
under the "options:" stanza, but there was no difference in behaviour.

Am I missing something in the intent of these parameters?

Regards,

Rogan
