Hi,
I have a feedback concerning CoolTerm. In the options we can
set delays (from 1ms to xxms) for sending data or packet of data (Use transmit line delay and Use transmit character delay).
These minimum delays are not optimal. We could have the possibility to select smaller ones (i.e. resolution of 100us).
This because we often connect rs232 terminals via FTDI chips (USB-to-RS232). These chips allow really fast connections,
but often too fast for small microcontroller targets (i.e. ARM cortex m3). 1ms of delays are
unfortunately too long and don't allow to exploit correctly the bandwidth of the channel.
Thank you,
Regards, Edo

A resolution of less than 1ms is already possible. ms is the unit in which the delays are displayed, but you can specify fractions of ms. I.e., if you want to specify a delay of e.g. 100us, simply enter 0.1.
