Did those different noises mean anything or were they just to make you think you were doing something all computery?

The first one dialling are DTMF tones for the local exchange to dial your number.

The high pitch tones are the two modems negotiating what speeds they can both run. V.22 (2400 baud), v26, v27, v32 running a mighty 9600, v.32 bis took a step to 14.4kbits/s. Then v34 up to the heady heights of 33.6. (Motorola Codex Modems were perfect for this on stty telephone lines from abroad). If you get passed all these you might be able to run at V.90 which was amazingly for its time 56Kbits.
