using telnet on port 80 to sent alive packet

I am using wget on other Linux based systems to report periodically the ‘alive’ status of a router. The wget message contains a few unique parameters, identifying the unit by mac address, the timestamp and the system load and maybe some other parameters. Since wget is not available in RouterOS, I thought I can use “telnet hostip 80” and then write the http commands directly into a script. But I have not yet figured out how to write that in a RouterOS script.

e.g.
/system telnet 192.168.0.1 80
telnet is now expecting input:
GET /alive.php?mac=00:01…&up=2006-05-08%2023:15:00

Any hints on that?

Or how to use wget in a script? wget is part of busybox. RouterOS is using busybox, but wget seems to be not included in this version.
