Missing features

Very nice little utility!
Now you should implement "noisy" lines (spurious characters) or error correction emulation (speed will not be constant depending on noisiness).
Full model emulation would be very nice also 😃

What would such noise look like? I have never used an actual teletype or serial terminal.

Another feature would be compression such as V.42bis or V.44. This one is tricky because compression takes computational time and speed of such may need to be adjustable. However important because 2400 BPS modems and above almost always had compression and it was working really well. From my own experience text operations (unlike file transfers for example) were compressing very well and 2400 BPS V.42bis modem was almost same speed as 9600 without compression (again for text/shell work only).
