comm <asy_iface> <"text_string">

     Sends "text_string", followed by a CR character, to the specified
asynch interface.  Normally, this command is used to place a TNC into
KISS mode when Jnos is started, but it may also be useful to send AT
commands to attached phone modems.

Example 1:  Ensure kiss mode is on:
     comm tnc "kiss on"
     comm tnc "restart"
     pause 4
     param tnc txdelay 10

Example 2:  have telephone modem answer on first ring:
     param dialup up
     comm dialup "atz e0 s0=1"
     pause 2
     start tip dialup modem 360
