Serial Port support

Please can a

[/write "Text" port=serial0]  be made available for sending a text string to a device connected to the Com/Serial0 port. And even better a facility to receive an "OK" from the connected device. There are many "sms" type communicators that do not comply with the int. standard for input strings and need a unique text command string. 
I have tried the "dirty" workaround using a ppp client and the modem "Init-string" but it is not reliable and appears not to work at all in V5.2.
