It is reading from stdin, i.e. your terminal, and thus doesn't freeze but waits for your input. On top, there's a done missing for your while loop.

TERM(1) 						      General Commands Manual							   TERM(1)

NAME
term - turn PC into a dumb terminal [IBM] SYNOPSIS
term [baudrate] [parity] [bits_per_character] [-dial_string] [device] EXAMPLES
term 2400 # Talk to modem at 2400 baud term 1200 7 even # 1200 baud, 7 bits/char, even parity term 8 9600 /dev/tty01 # 9600 baud, 8 bits/char, no parity, use tty01 term -atdt12345 /dev/tty01 # Start with a command to dial out DESCRIPTION
Term allows MINIX to talk to a terminal or modem over RS232 port 1. The program first sets the baudrate, parity and character length, and then forks. The parent sits in a loop copying from stdin (usually the console's keyboard), to the terminal or modem (/dev/tty00). The child sits in a loop copying from the terminal or modem (/dev/tty00) to standard output. Thus when RS232 port 1 is connected to a modem, every keystroke typed on the keyboard is sent to the modem, and every character arriving from the modem is displayed. Standard input and output may be redirected, to provide a primitive file transfer program, with no checking. Any argument that starts with a minus ('-') is sent out to the modem, usually to dial out. Term accepts several commands that are formed by typing the escape character, CTRL-], and a letter. Type CTRL-]? to see a list of commands. The subshell command is very important, it allows you to type in a ZMODEM command to transfer data. Do not quit term to do this, or your modem line will be reset! Term keeps the modem line open on file descriptor 9 while running the subshell, so you can type <&9 >&9 at the end of your ZMODEM command to connect it to the modem. Important note: to use term, it is essential that /etc/ttytab is configured so that there is no shell hanging on /dev/tty01. If there is, both the shell and term will try to read from /dev/tty01, and nothing will work. SEE ALSO
