c: Call Up a Stored Form and Set the Automatic Transmit Buffer Length
Note:
Expanded functions are case-sensitive.
Expanded Function c is a non-form message that calls up a stored form and sets the automatic
transmit buffer length in the same transmission.
transmit buffer length in the same transmission.
Rule: This function must be followed with two extra characters: Automatic
transmit buffer length character and a form identifier character. The form
identifier character is a printable character of the ASCII subset. The form
identifier follows the automatic transmit buffer length character.
identifier character is a printable character of the ASCII subset. The form
identifier follows the automatic transmit buffer length character.
Rule: Do not use Expanded Function c to call up a form that has a number
symbol # as the third text character. This type of form has an automatic
transmit buffer length as an integral part of the form. The automatic
transmit buffer length assigned with the number symbol overrides the
buffer length that you are trying to assign with Expanded Function c.

transmit buffer length assigned with the number symbol overrides the
buffer length that you are trying to assign with Expanded Function c.
What Happens
This function copies the identified form from the stored form file into the form buffer and then
into the DOS terminal’s compose buffer. Expanded Function c also sets the automatic transmit
buffer length. See “Automatic Transmit Buffer Length” in Appendix C, “Code Tables and
Character Sets”, for hex values of the buffer length characters.

buffer length. See “Automatic Transmit Buffer Length” in Appendix C, “Code Tables and
Character Sets”, for hex values of the buffer length characters.
The form remains in the form buffer until the host computer or DOS terminal operator replaces or
deletes the form. See Expanded Function K for more information on stored forms.
deletes the form. See Expanded Function K for more information on stored forms.
Application
You can use Expanded Function c when you wish to assign a buffer length to a stored form that
does not already have a buffer length associated with it. By using a stored form rather than
sending the whole form from the host computer, it reduces the amount of traffic on the RF
channel.
